February is Horsetail Fall Month

Back in 1989, for Christmas, my aunt gave me a copy of Galen Rowell’s “The Yosemite”. Actually – I saw the book in a local bookstore and asked her if she could get it for me for Christmas. My guess is that there was a sigh of relief from my aunt – knowing that year’s present was going to be easier than trying to figure out the latest fashion in clothing she’d try to get for me. Needless to say, my aunt’s gift that Christmas changed my life forever. It got me into landscape photography!

Galen’s book paired his photographs alongside the energetic words of John Muir’s book “The Yosemite” – the goal to hopefully melt a pictorial inspiration with Muir’s prose. Well, it worked for me! Not only did the book inspire me to pick up a camera, but Muir’s words inspired me to want to “Climb the [Sierra] mountains and get their good tidings” and go visit Yosemite, which I hadn’t yet (I was 19).

I would pour over Galen’s book, sometimes for hours, in amazement of the beauty of Yosemite he captured through his camera.  The one image that burns red in my mind from that book was his ‘Last Light on Horsetail Fall, El Capitan, 1973’ (click on the AA0008 image).  I stared at that image for what seemed an eternity the first time I saw it!  “That fall is real?” I asked myself.

It took over twenty years and numerous visits to the park before I got to witness and capture Horsetail Fall through my camera.  Nearly a year after I arrived to Yosemite, I nestled my camera amongst the many who showed up one night in February of 2011 to try to capture the glowing fall.  Unfortunately, not all the conditions showed up to stoke up the ‘natural firefall’ – clouds to the west hid the red light at sunset and foiled all our attempts to capture red water careening down the east face of El Capitan.

In order for the orange/red glow to happen, several things need to align.  First, there needs to be enough water in the fall, which is fed by snow-melt on top of El Capitan.  Second, if it is stormy, with clouds surrounding the cliffs, or if there are clouds to the west that block the sun at its lowest point before setting (as was my case in 2011), no go.  February is typically a stormy month, so getting the ideal conditions for this event could take years.

Fortunately, my good friend and fellow photographer, Michael Frye, has devoted considerable time to figuring out the ideal days for photographing Horsetail Falls.  You can read his article here.  He has deciphered that the best window for optimal light is February 16 – 23.  Photographing before this can still capture glowing light, but the sun hits to the left of the fall at sunset, as in my picture below, taken February 3rd.

Horsetail Fall, February 15th, 2012.

Horsetail Fall, February 15th, 2012.  Notice most of the light is still to the left of the fall, but enough (but not a lot) water is in the fall to see it glowing, particularly on the bottom part, just before is descends behind the dark ridge in front of it.

Horsetail Falls, February 17, 2012, 5:28 pm

Horsetail Falls, February 17, 2012, 5:28 pm.  This was taken right in Michael Frye’s optimal window.  Notice the light is just hitting the fall.

This highlights the cliff, with the fall in shadow at sunset.  Photographing after the 23rd, the sun then hits the wall to the right of the fall – again, the fall is lost in the darkness of the cliff.  Having the left-side cliff in shadow really makes the waterfall ‘pop’ with color – like putting a dark sheet behind a light subject in a portrait photograph.  Frye writes, “I always felt that the shadow behind the cliff is an important element”.

So, there is one week of opportunity to capture the sun just hitting the water – not much of a window.  Thanks to Michael Frye, photographers can now plan their trip to Yosemite around the optimal week in February to photograph what Frye believes is the only glowing waterfall of its type in the World.  Thankfully, working here as an Ansel Adams staff photographer gives me access and daily opportunities to try to capture a rare (and hopefully unique) ‘natural firefall’.  I will most certainly be staying home February 16 – 23!

Speaking of Ansel Adams – Did he capture the ‘natural firefall’?  The answer is yes, but since he was a black & white photographer, his emphasis was on the falls’ back-lit spray.  Steve Bumgardner, producer of Yosemite Nature Notes, has a wonderful video explaining the photographic history of this fall.  In it, Michael Adams, Ansel’s son, remembers the fall as El Capitan Fall, and shows a picture Ansel took of the fall with lots of water in it.  So, Ansel did capture Horsetail Falls and rendered it’s beauty perfectly in black & white.

Conditions update February 5th:  A dry January has left little snow on the top of El Capitan to feed Horsetail.  The latest forecast calls for a little precipitation this week

7-Day weather outlook as of February 5th.

NOAA 7-Day weather outlook as of February 5th.  We have 1 – 3 inches of snow expected on Thursday.  We need more though!

We really need at least one big storm, I believe, to get the fall going well enough in two weeks.

Hope to see you out there this year!

Stop. Look Big. Yell. Bear safety that really works.

Adolescent Bears in Oak Tree, Yosemite National Park

Adolescent Bears in an Oak Tree, Yosemite National Park

I love trail running!  Since my move to Yosemite in 2010, I get to run in one of the most beautiful, scenic mountain ranges in the world.  Not only does Yosemite National Park offer many trails, but the National Forest surrounding the park offers equal prospects for trail running – most times without the crowds that I encounter in Yosemite Valley during the summer season.  The National Forest also offers opportunities to encounter wildlife not tamed by over four million visitors that now visit Yosemite each year.  With solo wilderness backcountry trail running, there is a responsibility of protecting oneself in the event of an encounter with large animals such as mountain lions and bears.

Recently, my girlfriend Shauna introduced me to an amazing grove of sequoias near her house.   The Nelder Grove is just outside the southern entrance to Yosemite and is managed by the US National Forest Service.  It has quickly become one of my favorite places to photograph, cross-bike ride, and trail run.  It has a short loop trail with several amazing sequoias, including the Bull Buck Tree – one of the largest sequoias in the grove.  A longer, three-plus mile trail takes one up to a smaller grove at the top of a ridge and is more secluded than the loop.

Back in July, I decided to do my first solo trail run on the longer trail to try and beat the triple-digit heat occurring in Oakhurst; hoping the shaded trail and higher elevation (5000’ – 6000’) would bring some relief.  This proved to be true when I emerged from my car at the trailhead.  After some stretching, I took off on the trail – headed for the upper sequoia grove.  I quickly noticed the silence and solitude offered by being on this trail – on a weekend in the middle of the summer.  It didn’t take long before I was enjoying my run, getting into a rhythmic groove as I was reaching the first mile.

Suddenly, from my right side, my silence and solitude quickly vanished with a lumbering noise approaching me; a mostly breathy “rah, rah, rah, rah!!”.  I looked to my right and on the uphill side of the trail, running right toward me, was a rather large mama black bear with two cubs in tow.  The cubs quickly jumped and scaled up the nearest pine while mom continued her charge right at me.

This was one of those moments that I knew was a possibility yet, had never actually prepared for really happening – a mama bear with cubs, protecting her young by charging at a perceived threat.  I’ve read many times about what to do in this situation:  Stop, make yourself look as big as possible, and make as loud a noise as possible, and if there’s anything to throw, pick it up and throw it at the bear.

My first instinct was to run faster.  With something 300 – 500 pounds faced squarely upon you, threatening harm, wouldn’t you?  I resisted that instinct and stopped.  I looked around for something to pick up and throw.  Nothing was nearby me unless I ran to get it – probably not a good idea with a sprinting bear coming at me.  So, I got past my fear, looked directly at the approaching bear, put my arms over my head to look big, and began to roar as loud as I possibly could.  Mind you; this was all happening in the span of about 5 seconds.

There was a moment after I started, mama bear still charging me, where I thought, “This might be it.  This creature might cause some pretty bad damage to me…or worse!”  I kept up with the roaring and with less than ten feet to spare, the bear stopped at the top of the uphill berm of the trail – looking right at me with her ears straight up, eyes intently looking into mine.

This bear was wild.  Not like any bears I’ve seen in Yosemite Valley.  First, it didn’t have the tell-tale ear tag that nearly all bears in Yosemite Valley have.

Secondly, most Yosemite bears have become accustomed to people and vehicles, and do not seem to be as affected by human presence.  I remember once seeing a mother bear and two cubs walking towards me to El Capitan Meadow one evening.  Just before crossing Northside Drive to get into the meadow proper, cars began to stop, people getting out of their cars in the middle of the road to photograph or video these bears – creating what Yosemite locals call a ‘bear jam’.    This was my first witness to the rather normal summer event.  I noticed mama bear quickly turned her cubs around and headed back into the forested region near the base of El Capitan.  I felt no fear from my photographic position in the meadow – a position that the three bears were aiming for.  I think I knew they’d turn back, so continued with my evening shoot.

Many times I’ve witnessed Yosemite bears crossing roads, innocuously turning logs in the forest, running through North Pines campground being chased by a camper who’s yelling, “Go Bear…Go!”.  I’ve come to view these large mammals as mostly harmless; certainly appearing to not be interested in taking a bite out of or swatting any humans with their ginormous paws and sharp claws.

But this was different.  Standing eye to eye with this bear was humbling.  She could have ripped me to shreds if she wanted.  I was utterly defenseless, except for my wits.  I looked her square in the eyes and roared like I’ve never done before; like I was going to rip her to shreds if she came closer (at least that was the role I was playing).

It worked!  She turned around and ran back to where she came from, her cubs coming down from their safe trees and running behind her.  She continued to run until about 100 yards from me where she turned, looked at me, and then continued to lumber away.  Let me remind you – I was still yelling.

Weirdly enough, perhaps with a bit of “I beat her”, I continued up the trail with my run, running a few seconds faster than previously; mostly from adrenaline and less from fear of bears.  Since my run was not a loop, I had to revisit the place of the incident.  As I ran past, I made several loud grunt noises; as if to state that I was back and to not mess with me.  This was clearly an attempt at putting myself at ease, as I did NOT want to have another charging bear face-off.  Luckily, this time it was just me on the trail with a handful of gray squirrels and chipmunks scrambling up trees nearby.

I learned two valuable lessons from my bear encounter.  First, all the preparation for the remote possibility of an encounter with mountain lions and bears is very much worth the effort.  Second, and most importantly, believing in myself enough to stand my ground in the face of imminent danger was a life lesson that mama bear indirectly gave to me.  There might be times in my future where a challenging event may come again.  I believe that this encounter has prepared me and will help remind me to stand my ground and be completely present with whatever situation I am presented with.  Being confident in the face of adversity is a life lesson we all must learn and five hundred pounds of charging, life-threatening, female-protecting bear energy reminded me of this.  Thank you mama bear!!

The Glacier Trips: Final Story, October 2012

Here it is – the final installment of my blog series about Yosemite’s glaciers.  Thank you for following and I hope you enjoyed the series!  If you’d like to read the first three posts to this story, click here.

October Glacier Trip

The first weekend in October found me again, hiking the long trail from Tuolumne Meadows through the beautiful Lyell Canyon.  My destination – The fourth and final encounter of this year, with Yosemite’s remaining glaciers.  I decided to hike ahead of the survey team for this trip; partly to experience the hike solo, but also to have additional time to photograph places along the trail I had been wanting to connect with—and had spotted on previous trips.  It was a beautiful day!  I stopped several times for photographic opportunities.  Below, I think, exemplifies early fall in Yosemite’s high country.

I met up with the team later in the afternoon and we headed for our previous campsite during the September survey.  Volunteering for this trip was Greg Stock’s wife Sarah Stock, Brian Whitehead, Matt Holly, Jessica Thompson, Jen Jackson, and Dustin Garrison.  Arriving to camp before dinner gave us plenty of time to set up camp, eat, and watch one of the Sierra’s finest light shows!

This trip was simply to get one more velocity measurement from the stakes in both glaciers, then take the stakes out and complete the four-year study.  We headed for the Maclure glacier first.  Freezing night temperatures helped keep the stakes in place, which made for easy measuring and removal (except for two stakes frozen in the ice).  Again, the weather was very good, so working during the day was a pleasure and sleeping at night was very restful.

For this trip, I could only work until noon on the first day.  This was because I had also been monitoring the development of the fall leaf color progress on the eastside and thought it might peak during this same weekend; thus, the plan was that I would leave the glacier trip a day early.  Greg and I connected after the weekend and he informed me that measurements on the Lyell Glacier were equally easy as on the Maclure.

If you read my previous blog, you will remember that I have initial findings from the survey that Greg Stock said would be appropriate for me to share and publish here.  Here they are!  First – the good news.  A recent correspondence with Greg revealed current velocity measurements of the Maclure Glacier:  “The Maclure Glacier moves about 22 feet per year, with somewhat faster motion in the summer than in the winter.  Our August-October measurements were indeed very similar to Muir’s, with about one inch per day of movement.”  Greg added that he and geologist Bob Anderson (the other part of the study team on the survey) are puzzled by the movement because the glacier is 60% smaller than the 1872 Muir study “with about 120 feet of vertical ice loss”.  The glacier is still moving and during our July trip, a few of us heard and felt the glacier’s bass-like creaking and popping sounds that seemed to indicate that movement was occurring underneath our feet – somewhat unsettling sounds when on the glacier!

By contrast, the data collected from the Lyell Glacier tells a very different story.  From July – October, Greg’s velocity measurements showed that the Lyell had no movement…at all!  Even with the Lyell’s larger surface area, making it visually the largest glacier in the park (and one of the largest in the Sierra), the data suggests dramatic change.  I’ll remind you once again that in order for a glacier to be called such, it needs movement.  It must have enough mass to keep that movement going and continued formation of ice to maintain the previous two.    The recent survey’s numbers were also gathered during a season in which a Sierra glaciers’ movement would be the greatest – during the summer months (as Greg stated above).

All the Lyell’s information puts Yosemite National Park’s first appointed geologist to the task of what to call the large ice structure below the northern slopes of the highest peak in the park.  As I write this, Greg is writing his report on the four-year glacier study, no doubt checking over the stats once more and finalizing his conclusions.  Computer models will be created to help interpret the data more easily to park service officials and the public.  “One thing is for sure”, Greg points out during one of the survey trips, “The news that’s revealed from this will be big!”  Greg has the report’s tentative finish date sometime in early 2013.

Being the 2012 glacier survey’s regular photographer was exceptional!  Not only did I get to travel to one of the most beautiful places in the park, but the opportunity helped to augment my photography skills.  This was the first time I had the chance to document an event, in addition to creating artful photographs.  As seen from my website’s portfolio – there are no humans in my photographs.  It was great to test this new territory.  I learned a lot and perhaps this is only the beginning.  I am also eternally grateful to Greg Stock for allowing me the chance to be a part of this historic survey.  Not only have I gotten to know him better, but I got to meet many volunteers who, like me, share a fascination of glacial geology and wanted to know first-hand what is going on with Yosemite’s glaciers.  Meeting Colorado University, Boulder’s Bob Anderson was equally great, as he had much additional glacial information and enthusiasm to share.

It is also important to note that this isn’t the only recent study of Yosemite’s glaciers.  Hassan Basajic studied many of the Sierra Nevada glaciers and wrote an impressive report on his findings, which you can read here. Of considerable interest for me was Hassan’s use of comparing old photos of the glaciers with his new ones taken in the exact location of the old photos to show visual evidence of the glaciers’ retreats.

I can’t speak for all who participated, but I can say that this experience not only informed me of the current conditions of these ice formations, but it has helped me see the direct effects of climate change in my back yard.  For me, climate change is now more real than ever.  Learning the truth about these glaciers is emotional.  I feel a profound sadness for the loss of these incredible moving bodies of ice.  For now, I can say, “At least the Maclure is still moving”.  But, for how much longer?  Perhaps I can take comfort in the fact that the Sierra glaciers have been growing and retreating, disappearing and reappearing throughout the range’s history.  Maybe, thousands of years from now, the very spot I write this blog from in Yosemite Village will once again be under meters of ice, experiencing the day-to-day ablation of yet another glacial period; erasing any signs of The Ansel Adams Gallery, the scoured Ahwahneechee acorn grinding stones, and possibly even the vertical walls of Half Dome and El Capitan.

The future remains to be seen.

For now though, I have witnessed first-hand and documented through my camera, another diminishing ecosystem caused by our present-day, human-caused, warming planet.  How will this affect all the species, including us, who rely on this resource?  Maybe I should be happy for experiencing these glaciers while they are still here; believe me – I am! Yet, as I look to the future and ponder the National Park Service’s Mission Statement, “… to conserve the scenery and the natural (my emphasis) and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.”, I am left with an emptiness that the coming generations will experience a Yosemite impaired; a Yosemite without glaciers. A Yosemite wilderness not mismanaged by its faithful and evolving National Park Service, but by forces much larger than itself—forces that are collective and know no boundaries.

The Glacier Trips: September 2013

My Apologies for not getting these stories out sooner!  I had an incredibly busy October and time got away from me to write.  With that, enjoy the remaining glacier blog posts!

September Glacier Trip

Park Geologist Greg Stock uploading temperature data to his small laptop.  This gauge has been out in the field since the beginning of the glacier study in 2008.

September’s glacier trip found me on the ice with a team of six volunteers, Colorado University,  Boulder geology professor Robert Anderson (the other institution involved with the glacier study), and of course, Yosemite National Park geologist Greg Stock.  The goals this month:  Record the position of glacier stakes since August and begin the removal of equipment from the area, as the study’s end is the first week of October.  In addition, stream and temperature gauge data was downloaded, as part of a water discharge study, and then the equipment was removed, per Leave No Trace wilderness principles.  The biggest piece of equipment removed was the meteorological station (MET station for short), which has recorded weather data in the region since the early days of the glacier study nearly 4 years ago.  After the final data was collected onto Greg’s laptop, the MET station was dismantled, divided up amongst the volunteers, carried down to base camp and eventually out of the back-country.

Volunteers Brina Mocsny and Scott Borden help dismantle the meteorological station with Colorado University, Boulder professor Bob Anderson (pictured with light cap).

Cooler September temperatures slowed glacial ablation enough to hold six of seven stakes in their positions, making measurements far easier than August.  Still, we had to drill the holes deeper to ensure they would be intact to measure on our final October trip.  While on the Lyell glacier, I wanted to make sure to photograph a marker on a rock face – a ‘K’ – which marked where the glacier’s surface was during a 1933 survey .  I was very interested in knowing the elevation difference between the ‘K’ and the current glacier surface, now below it.  Professor Anderson loaned me his lazer rangefinding device to get this distance.  I walked over to a spot (see below photo), found a piece of exposed ice at the end of the glacier, got down at ice level, and shot the lazer right at the ‘K’.  40 vertical meters came back (approx. 130 feet).

Brina helps give human scale to 79 years of glacial retreat.

So, between 1933 and 2012, the Lyell glacier lost around 130 vertical feet of ice from my position.  To put this in perspective, imagine you were walking on the Lyell glacier in 1933.  You would be 130 feet above my head, more or less, a massive ice sheet between you and me!  It’s not there anymore.  In 79 years, all that ice has melted away.  With 2012 California and national temperatures breaking records for more consecutive highs each year, these conditions seem to point towards more melting.

The most important analysis, however, will be the data collected from the stakes off both the Lyell and Maclure glaciers.  Reading my first blog post from this project, you will remember that in order for a glacier to be considered such, it needs to have enough mass to move.  If it’s not moving, it would be considered more of an ice field than a glacier.

A conversation with Greg revealed even more interesting glacier facts.  The Sierra glaciers have oscillated in behavior throughout the mountain range’s lifetime.  Glaciers have grown and retreated several times.  Greg even mentioned that at one point, glaciers were completely absent from the range.  He emphasized that these oscillations have had thousands of years of regularity between them.  By contrast, this last retreat to present time took only 150 years of time – extremely out of the norm and notably beginning the same time as the Industrial Revolution (roughly 1850); the time when burning fossil fuels and releasing C02 into the atmosphere began in earnest by humans.    “The last 150 years”, Greg points out, “is very much out of [geological] regularity of past Sierra glacial retreats.”

Having finished this trip’s work on the Lyell, the team hiked to the Maclure region the next day for measurements and some clean-up of old stakes, left behind from previous glacier studies, dating as far back as the 1970’s.  Similar stake conditions to the Lyell made for easy lazer rangefinder measuring and re-drilling of the stake holes.  This day found me walking alongside professor Robert (Bob) Anderson, using an ice auger to make the stake holes deeper and holding a prism above the stakes for Greg to get distance measurements from his lazer rangefinding station at the base of the glacier.

Professor Bob Anderson holds a prism to capture the lazer rangefinding beam and send it back to Greg Stock at a fixed position below.

Bob was a pleasure to work with and listen to!  He has previous experience working with glaciers at Glacier National Park and told the group stories about being underneath glaciers, setting up monitoring equipment.  He also worked on Colorado glaciers and had just returned from Alaska studying glaciers there before our trip.  He was grateful for my camera knowledge – especially when I turned on the Highlight indicator in his Nikon camera.  In Bob’s spare time, he enjoys photography and still employs his 4X5 medium format film camera to capture images.

Speaking of being underneath glaciers…After the team was finished with our Maclure Glacier work, Greg took us to one of the Maclure’s amazing wonders – its ice caves!  We entered two at the toe of the glacier and a whole different world revealed itself!  We were on newly scraped rock, covered with glacial flour, while the bottom of the glacier was the roof of the cave.  This world stayed at a constant temperature around 32 degrees Fahrenheit, allowing for all sorts of ice forms to be present.  The pictures below show a few of the things seen there.  Going into the Maclure ice caves was not only a highlight of this trip, but a highlight of all my trips to the glaciers this year!

One last note:  Weather on this trip, while cooler and with more wind, was much more pleasant than the August trip (Read my blog post on the August Glacier Trip to see what happened then).  Clouds formed, but rain never fell.  Also, Shauna loaned me her two-person tent, which when pitched correctly, had no problems with the stiff winds we had and allowed me lots of room to keep my gear dry in case of rain.

With each glacier trip, I have gained more respect for Greg and Bob and the information that they are retrieving for their study.  I believe this knowledge will have a significant impact not only on the health of Yosemite’s remaining glaciers, but bring additional and unique awareness to the larger impacts of human-caused climate change.  Stay tuned for part two of this blog on October’s final glacier trip and for future posts when Greg’s final report is done!  The next post will also have initial findings from the survey – the first public writing of the results from your’s truly.  Historic!!

Early Signs of Fall Color on the East Side

Layers of Aspens, Green Creek, Eastern Sierra, October 2011

Shauna, her dog Roo, and myself went to check out the progress of fall color on the east side this weekend.  It was a great weekend with excellent weather.  Traveling along the Tioga Pass Road (Hwy. 120), we noticed a fair amount of people still visiting Yosemite’s high country – something that neither of us has seen in the past.  Usually, the high country has slowed some, but maybe with all this great weather, people are still trying to get that last backpack trip, or climb in, before it starts getting cold.

I wanted to show Shauna the June Lake Loop because she hadn’t been there yet.  As we drove around, early signs of fall in the aspens are showing.  Mostly, there is a slight yellowing to the leaves at this point, but there were a few trees in full fall color.  Sorry- didn’t get pics of that.

We then headed north to Lundy Canyon.  Similar Aspen conditions exist here, with the exception of one fairly large grouping of trees turning color up an eastern Sierra slope near Hwy. 395.  It’s been my experience that higher altitude aspens turn before the lower ones and I’ve seen them turn in mid to late September in the past.

Fall Color & Lundy Falls, Lundy Canyon, October 2011

It was fairly cold during the night at Lundy Creek Campground, but not freezing.  Theories suggest that really cold temps help to turn the leaves.  If that’s the case, it may be a couple more weeks before full color happens (perhaps 1st week of October – earlier than usual).  I’ll be returning in a few weeks in hopes of an early fall on the east side!

Kirk’s disclaimer:  I’m new at this prediction stuff, so in no way am I responsible for mis-predicting fall color.  Think of me as you would a weather person…  Check other east side fall color sites as October gets closer for more recent observations.  I’ll certainly update my blog the next time I’m on the east side!

August Glacier Trip

August 21st saw Park Geologist Greg Stock, assistant Colter Chisum and me heading back up to the glaciers to record their movement since July.  I was happy that my gal Shauna Potocky also came along, as she was meeting with trail crews at a nearby CCC camp, just off the PCT, to give them a presentation on her recent trip to Chile.

This glacier trip was designed to be a simple, fast, and light trip:  Hike in, measure movement of the stakes we put in the ice in July, and then hike out 24 hours later.  All of us brought light bivy sacks just in case we had some wet weather…more on that later.  One thing to note from the last month’s blog post – August 21st was the day that John Muir had placed stakes in the Maclure Glacier to do his personal research.  Greg’s goal was to duplicate measurement 140 years later to the day.

Park Geologist Greg Stock measures glacial water discharge in the Maclure Creek.

A fall on Maclure Creek. Maclure glacier is to the left, just out the picture.

Starting before 9am, we made good time and over 12 miles later Greg, Colter and I were at the foot of the Maclure Glacier by 4pm, where we met up with Yosemite Conservancy naturalist and educator Pete Devine (who is personally interested in Yosemite’s glaciers like me).

The first noticeable observation was the lack of snow on the glacier – nearly all the ice was exposed.  The Maclure in July had a fair amount of snow coverage.  The previous two weeks had seen temps above normal (Yosemite Valley, at 4000’, was in triple digits for nearly a week).  Greg’s unease about stakes melting out of the glacier were realized when we approached the lowest stake to find it lying on top of the glacier.  Greg estimated that the glacier had lost approximately 1.7 meters of glacial surface to ablation since the July trip.  Ultimately – we did not put the stakes in far enough!  Luckily, we had GPS locations for all the placements, plus rock cairns at nearly all of them, so we were able to find the original locations and re-drill the stakes into the ice.  So, a one hour job became a four hour job when we finished right as red sunlight was leaving Maclure Peak – achieving the data gathering on par with John Muir’s August 21, 1872 date.

Storm clouds gathering at sunset over Kuna Crest.

NOAA’s website predicted fair weather for our 2 days out.  Clouds began forming overhead as we sat down for our meal.  The skies were completely grey by the time we all went to bed, so we all decided to play it safe and rest inside our bivy sacks.  Hours past when I was awakened by drops hitting the netting of my bivy.  “No problem. I’ll just zip up the bivy and be dry while the rain falls.”  The rain got harder and harder and within an hour, a steady downpour ensued.  I noticed my sleeping bag was wet near one of my legs.  I turned on my headlamp and to my horror; the top of my bivy sack had delaminated from the bottom!  My sleeping bag was getting soaked!  Thinking fast, I flipped over my bivy and used it as a basic tarp.  It rained the whole night.  Luckily, the temperature wasn’t too cold, so I threw on all my warm clothes and had a very wet, clammy night with maybe 2-3 hours’ sleep.

My bivy sack after the storm – The red, top part of the bivy delaminated from the black bottom. Luckily, the bottom was big enough to use as a tarp to drape over myself!

The four of us awoke at 7am.  Come to find out, no one had a restful sleep.  Greg got wet in his bivy and had to move out of a pool of water that formed around him.  So, we shrugged our shoulders, ate our breakfast and got ready to hike over to the Lyell to measure the stakes there.

Some stakes had melted out of the Lyell, but some were still in the ice – better than expected from the previous day’s discoveries.  Greg had also found two stakes from his 2010 survey that were still in the glacier, so we added the measurements of those to the five we placed there in July.  Success!!

Rain clouds formed again and by the time we finished the rain was falling.  Gratefully, we all descended back to the PCT safely.  Greg, Colter, and Pete continued to hike the remaining 11 miles out while I stayed with Shauna near the CCC camp one more night.

Even with equipment failure and unforeseen stake melt-out, the August trip was fruitful.  September’s trip is just a few weeks away.  I look forward to updating you with the results from this trip.  Let’s all wish for a dryer trip!

Photographing and Studying Glaciers with Park Geologist Greg Stock

From July 9th – 12th I backpacked twenty-two-plus miles with park geologist Greg Stock to some of the highest peaks in Yosemite, Mt Lyell (13,120 ft.) and Mt. Maclure (12,880 ft.), as part of a survey to measure movement of each mountain’s glacier.  This trip has been a long time coming for myself – A shoulder injury kept me from going last year.  Ever since my geology studies in college, I’ve wanted to take a trip to a Sierra glacier.  Not only can I say that I’ve completed that wish, but now I’m going back – 3 more times to be exact!

The National Park Service, along with the University of Colorado, has been conducting a three-year study on the movement of these glaciers; trying to determine if they are still moving and, if so, what their total movement is per year.  According to Stock, both glaciers – along with all the Sierra glaciers – have melted substantially, or have disappeared completely since the last Little Ice Age, which he said ended sometime around 1850.  Ultimately, the results of the study will help  determine if Yosemite’s remaining two glaciers can be considered ‘living’ or ‘dead’ glaciers.  For a glacier to be called a glacier, it must have consistent, down-slope motion and enough mass to keep that movement going; thus a ‘living’ glacier.  If a glacier no longer has the mass to move and doesn’t get enough snow to replenish the ice mass, it is considered a ‘dead’ glacier.  Determining if either or both glaciers are dead will be historical for Yosemite’s last ice flows and could lend more mounting evidence for the existence of global climate change.

Park Geologist Greg Stock drilling a stake hole on the Lyell Glacier. The five stakes inserted into the Lyell Glacier will be measured at a fixed point each month to determine movement of the glacier.

The field study, started in 2008 (delayed a year by larger than average snowfall in 2011), is completing this October, with the final report out sometime in 2013.  This study is culminating exactly 140 years after John Muir, from his own curiosity, measured the velocity of the Maclure Glacier from August to October of 1872 by inserting stakes into the glacier.  Part of the study – a piece that excites Stock – is to duplicate Muir’s measurement dates in August and October.  Stock is returning to the glaciers two additional months – July and September – to add additional data to the final velocity measurements; ultimately refining Muir’s methods from his 1872 study.

As a staff photographer for The Ansel Adams Gallery, my interest in this study comes, at one point, from being in the footsteps of Ansel.  From his early days working his first job as summer caretaker for The Sierra Club’s LeCont Memorial; evolving to be on the board of directors from 1937 – 1971, to his large volume of writing to save wild lands, Ansel was one of the early environmentalists.  I am honored to say I work for an institution that was started by someone who loved wilderness so much!

Like Ansel, I fell in love with the Sierra at a young age.  Like Ansel, I want to capture magical Yosemite and Sierra moments with my camera.  I also feel compelled to understand our increasingly changing planet through the lens of my camera.  Monumental shifts in Glacial ice in Greenland; The Northwest Passage opening up more and more each summer; The American Heartland’s historic crop losses; Ever more intense storms and heat waves – All lend a heavy hand of evidence toward what scientists have predicted for decades – a warming planet.  Volunteering with the park geologist fills that part of me interested in knowing the truth of things.  And I want to know the fate of the glaciers in my back yard.  I feel I’m getting a sense of it now, but will wait for the data to be collected, the numbers to be crunched, and the last word of the report to be written before any definitive answer can be told.

Back to my camera comment above.  I have the pleasure of being the only photographer for these trips.  Not only am I documenting the glacier study process, but I get to photograph the beauty of the Lyell and Maclure area.  This first glacier trip has been truly inspirational for me and I look forward to taking part in the remaining glacier trips.  A big ‘Shout Out’ to Yosemite Park geologist Greg Stock for allowing me to be a part of this historic study and letting me literally dig the holes for the stakes and help with recording the data.  Stay tuned for pictures from the August trip!

A GPS location of the stakes is recorded to help locate its position if the stake is not found on a later trip.

It’s not all work on the glacier! Volunteer Jonathan Byers takes a moment to recuperate from drilling stake holes on the Maclure Glacier.

While much of the glacier trip was work, I got to do some ‘art’ photography as well. This is one of my favorite pics during a morning shoot before going to the Maclure Glacier.

My New Website…Finally!

Hi Folks –

Finally, after much prodding from my family, girlfriend, and friends, I have a website!  It’s in the beginning stages, but eventually this site will be a place where you can look at my gallery of photographs, purchase prints, keep up to date on what’s happening in Yosemite photographically, and read my latest musings.  Thanks so much for all the support you’ve given me throughout the years and I look forward to the progression of my photographic career!!

Here’s my latest photograph, Taken June 15th.  Yosemite Valley in early Summer dawns a green coat.  All the meadows, laden with water from the Spring snow melt, transform from dead brown to a very live green color.  This year, however, we had less-than-normal precipitation, along with a warm Spring, resulting in snow melting in the high country nearly a month ahead of schedule.  This was in stark contrast to last year’s record snowfall, which resulted in an extended Winter and Spring.  I looked at the water stats from last year on June 16th, versus this year – what a difference!  The Merced River on June 16th of last year was predicted to be at its flood stage level of 10ft.  Litig Meadow (S.W. of Yosemite Lodge) looked like a lake and the river was inches below Swinging Bridge, with very swift water running underneath.  This year by comparison – the Merced River was just under 3 feet!

On June 15th, we had a thunderstorm roll through the Valley.  I usually get excited, hoping for a unique, cloudy sunset to photograph.  The clouds went away before sunset, so I decided to try to find something unique anyways.  I went up-river from Swinging Bridge to find Sentinel Rock nicely reflected in the Merced, with the water low enough to see riverbed rocks within the reflection.  I had to move quickly before the light left the top of Sentinel, but was able to compose and snap off a few exposures.  I love the layers of colors and rocks!

Check back soon as I begin writing about my trip to the Lyell Glacier in early July with park geologist Greg Stock.   I’m very excited to be a part of his group, but mostly excited to see for the first time one of Yosemite’s remaining glaciers.  Yes…photographs will be taken!!
