The “Less” White One: Mt. Baker and the Ever-Shrinking Easton Glacier

You’ll notice that the Sun is shining brightly in all of these photos which should immediately tip you off to the fact that I’m several months behind in posting, since getting pictures this radiant at the present time would require either a a 200-mile drive east, or a 500-mile drive south. I’ll gripe more about that in a future post, rest assured.

One of the consequences of the copious winter precipitation here in the Pacific Northwest is the simply massive quantities of snow that pile up in the Cascades, just a half hour or so to the east of my current, comparatively temperate residence. In many areas, not all of that snow can melt the following summer and having more snow than you can melt is one of the key ingredients for a glacier. Almost all of Washington state north of Seattle has been covered by glaciers or ice sheets at some point in the last 20,000 years but nowadays the only glaciers remaining in WA are those high in the North Cascades and Olympics, and the tendrils of ice that snake down from the summits of the mightiest Cascade Range peaks; Mt. Rainier, Mt. Adams, Mt. St. Helens, Glacier Peak, and Mt. Baker.  Although the amount of glacial ice in Washington is getting ever smaller (Mt. St. Helens’ Crater Glacier is actually one of the few in the U.S. that is actually getting larger. Can you guess why?), according to the USGS Washington remains the 2nd most extensively glaciated state, 2nd only to Alaska. And they’re WAY further north so that’s sort of like cheating anyways.

The Easton Glacier on the southern slopes of Mt. Baker is one such glacier that has undergone rapid retreat over the past century. Covered by more than a dozen glaciers, Mt. Baker is an active volcano that was known by the Lummi as Koma Kulshan, which roughly translates to “Great White One”.  Mt. Baker experiences some of the largest annual snowfalls anywhere in the world, including a U.S. record 1,140 inches (that’s 95 feet!) during the winter of 1998-1999 according to NOAA. So how could its glaciers possibly be getting smaller with that much snow?  To understand that, we need to understand a bit more about how glaciers work. If you groaned at that last sentence and would rather skip ahead to the pictures at this point, go ahead. I won’t be offended. In fact, since this is a website, I won’t even know. But you’ll be missing a really great analogy that I use in just a bit here so you should probably just stick with me for another paragraph or two. Plus glaciers are really cool. Pun wholeheartedly intended.

Here’s the (very) quick and (very) dirty version: A glacier is a body of ice that flows downhill. During the winter, snow accumulates on the glacier, temporarily adding to its mass. When temperatures warm the next summer, the snow on the lower, warmer portion of the glacier will melt (as will some of the ice) but some of the snow on the upper, colder portions will survive and turn into ice, replenishing the glacier. If more ice is added in the upper part of the glacier than can melt in the lower part, then our glacier gets larger. If less ice is added than is lost, the glacier gets smaller. If they two equal, the glacier stays put. As hard as it might be to believe given the massive snowfall on Mt. Baker, rising global temperatures mean that in most years, the Baker glaciers lose more mass during the summer due to melting then they gain during the long, dreary, snowy winters. In geology speak, this is known as a “negative mass balance” and, if left unchecked, it spells doom for a glacier. Now, its completely normal for a glacier to have a negative mass balance year every once in a while. No biggie. Rather, it’s when negative becomes the new normal that the glacier will begin shrinking and will continue to shrink unless something changes to bring it back into balance.

Think of it this way: let’s say you wake up really hungry tomorrow morning and you decide to make yourself some bacon. Before you know it, you’ve gone right ahead and eaten that entire package of bacon all by yourself. I’m sure you can all empathize with THAT feeling.  Anyways, while that may not be the healthiest breakfast you’ve ever had, doing so once probably isn’t going to have much of an effect on your long-term health. You’ll go for a run the next day and burn those calories right back off, much like a glacier might experience a low-snowfall year followed by a record breaking snowfall the next year to make up for it. (Note: by now you’ve hopefully noticed that this analogy starts to break down when you consider that a glacier LOSES weight during a negative mass balance year…)  But if you start eating an entire package of bacon by yourself every few days, or even once a week, well….sad as it is to say, you might start having some serious health issues. Same is true for a glacier. If you lose mass one year, it probably won’t be that noticeable. But if temperatures increase, if the summer melting season becomes longer and you start losing mass year after year after year, then regardless of how much snow falls in the winter, it won’t take long before you start shrinking, and shrinking fast.

For example, here is a more expansive view of what the Easton Glacier and its surroundings looks like today:

EastonTrough

The long valley or trough stretching across the image represents the path carved out by the ice when the glacier was much larger than it is today. Just 25 years ago, much of the trough you see in the immediate foreground would have been filled with ice. The prominent ridge on the opposite side of the trough is a feature known as a “lateral moraine” (rhymes with “romaine” as in romaine lettuce, which I can emphatically say is far less tasty than bacon). A moraine consists of loose sediment that was once trapped within the ice. When a glacier is stable, i.e. when it doesn’t shrink or grow but rather sits in the same for an extended period of time, all that sediment gets deposited in large piles around the edges of the glacier when melting occurs. The presence of a moraine here tells us that the Easton Glacier once filled the entire trough to the level of the far ridge, and did so for a prolonged period of time. Considering that the ridge crest is more than 200 feet above the floor of the trough, we can see that not only is our glacier retreating, but that it was also once much thicker than it is today.

One way to get an estimate of how long the glacier has been gone from a particular area is to look at the vegetation (or lack thereof). While the time it takes for vegetation to sprout up in an area uncovered by a glacier varies widely (depending on factors such as soil development, climate, and species), often times smaller plants will begin to reestablish themselves within about 20 years or so of the glacier’s exit. In this case, much of the bare, brown/orange colored land in the center of the image was covered by ice as recently as the 1980s.  Even more amazing: follow the valley downhill to the right. Look how far down we have to go before we encounter even the slightest sign of grasses, much less trees. Scale is a little tricky in this picture but see that greenery way way down at the downhill end of the trough? That point is over a mile away from where the picture was taken and it happens to mark the approximate terminus of the glacier in the mid 1800s, near the end of a cool period known as the Little Ice Age. The Bellingham Herald has a nice article on the retreat of the Easton Glacier over the past 100 years, with spectacular photos comparing the modern glacier to how is appeared in 1912, here. As you can see, it is now a shell of its former self. Other glaciers on Mt. Baker are in a similar predicament.

Meltwater

Easton Glacier remains one of the easiest glaciers to access anywhere in the continental U.S. The toe of the glacier can be reached by hiking for about 2 miles along a moderately strenuous but well-maintained hiking trail. Eventually this trail crosses a wooden swing-bridge over the meltwater creek that issues from the glacier. From here, you simply head off trail and hike up the old glacial trough for an additional mile and a half or so (at the time of publication at least…) until you hit ice.  This part of the hike is decidedly more strenuous but as you can see from these photos, the scenery is spectacular!  Exploring the terminus of the glacier is fascinating! Huge piles of mud and debris deposited by the melting glacier cover the ice near the toe, masking the ice and making travel treacherous. A large meltwater stream emerges from the base of the glacier through one of these piles as if by magic. The ice near the terminus is heavily crevassed so one must tread carefully when hiking on the ice itself.

So next time you’re in the area, check it out before it’s gone entirely. Who knows, maybe you’ll even burn off the calories from that pound of bacon you ate for breakfast!

Rocky Mountain High…literally

When hiking, alone and sleepy, though a dark, pre-dawn, dense forest of tall lodgepole pine, every shadow and tree stump looks like a bear. It’s a great way to get your heart rate going early in the morning. I had risen from my restful (save for some early morning screaming and yelling coming from the campground across the road) sleep at 4:30 A.M. in an attempt to climb Colorado’s highest peak, Mt. Elbert, without getting myself electrocuted. I found myself mentally preparing to defend my White Chocolate Macadamia Nut ClifBar to the death at least half a dozen times over a 1 hour period. Not only is Mt. Elbert the highest point in Colorado, it is also the highest point in the Rocky Mountains as well as the 2nd highest point in the entire continental United States, just 65 feet lower than California’s Mt. Whitney.  Despite its height, the summit of Mt. Elbert can be reached via several well-traveled trails. All require a fair bit of elevation gain but the one I was forced to use as a result of not possessing a 4WD vehicle climbs 4,900 feet  in 4.5 miles, a healthy climb regardless of altitude.

Summer is generally considered a bad time to climb any peak that involves spending time above treeline because of the summer monsoon thunderstorms that are ubiquitous across the southwest. Unlike its Indian counterpart, the southwest monsoon generally doesn’t deposit several feet of rain on the surface (although they can produce some locally heavy, but brief, downpours) but they can, and often do, produce copious quantities of lightning. Lightning, as you most likely know, hits high places. Mt. Elbert is the highest point in Colorado. A person standing on Mt. Elbert, would then, by extension, temporarily be the highest thing still attached to the ground in Colorado. Put two and two together and you can see this makes for a potentially life-threatening situation.  The problem with these lightning storms is that they can develop incredibly rapidly and without warning out of clear blue sky. Your best chances of avoiding them is to hike early….really early.

I camped about 100 yards from the Mt. Elbert trailhead the night before the hike. A developed forest service campground was located directly across from the trailhead whose “services” I could utilized for $15 per night. Option #2 was to drive across the road and set up camp in a small clearing for $0 per night. The only things I would be missing (considering that I could simply walk across the road to use the water spigots) were the fire pit and picnic tables located in each developd campsite. Considering that I was alone (thus making a picnic table a bit unnecessary) and that a complete fire ban was in effect, I decided to save my hard-earned moolah.

Several vehicles were in the parking lot upon my arrival at 5 A.M.  By the midway point of the ascent, I had managed to pass all of these groups, save for a pack of Boy Scouts who had ascended beginning at 1 A.M. in order to see the sunrise from the summit. Lunatics. After about an hour or so of hiking through the forest, the Sun rose above the horizon just as I hit timberline at about 11,500 feet.  If you climb mountains on any regular basis, you’re probably aware that treeline on many peaks is a welcome sight. The lack of foliage generally provides reassurance that you’re almost there, in addition to providing spectacular vistas of the surrounding countryside. In other words, treeline often tells you: “Hang in there! Just a little bit longer!”

Treeline on Mt. Elbert invokes no such warm and fuzzy feelings. Rather, treeline on Mt. Elbert is merely a courtesy reminder that you are less than halfway there and that you still have more than 3,000 vertical feet to climb through ever decreasing oxygen levels. And the vistas aren’t anything to write home about from this point to boot.

Breaking out of the trees at 11,500’…still 3,000′ to go!

One of the few inhabitants of the upper mountain, the American Pika is a small, elusive rodent that call the scree slopes its humble home.

Mt. Elbert also redefines the term “false summit.”  Fortunately, for my sanity, I had thoroughly read a number of guidebooks and was well prepared for this matter. Good thing otherwise I probably would have consider hanging myself after reaching  the 2nd one and finding the true summit still out of my reach (fortunately, the lack of trees would have made this a tricky proposition…). On the way down, I encountered a number of weary and inquisitive hiking parties just below the lower-most and most evil false summit (still nearly 1000 vertical feet from the true summit) whom I regrettably had to inform that they still had a good hour or more of trudging to go. Judging by their reactions and creative use of profane adjectives, they were not as well-prepared for this as I was.

Nearing the first of the false summits. This one is particularly nasty since it is in plain view from the beginning of the trail.

Skirting around the edge of false summit #1, false summit #2 comes into view….

…and then the true summit finally appears on the horizon!

The view from the summit is, as would be expected, spectacular, although not necessarily any better than a number of other, lesser peaks in Colorado. Mountains fill the field of view as far as the eye can see in all directions. Several other Sawatch Range 14ers are visible from the summit including Colorado’s 2nd highest peak, Mt. Massive to the north (Mt. Massive is aptly named, it consists of four individual peaks of 14,000+feet along a 5 mile ridge) and La Plata Peak to the south. The view on a clear day (which it was) stretches all the way to Pikes Peak outside of Colorado Springs, almost 100 miles to the southeast, and the Maroon Bells outside of Aspen.  Being the first person apart from the overachieving group of scouts to summit that morning, I had the place all to myself for about half an hour. By the time summit-er #2 showed up at about quarter to 9, clouds were already starting to build up around the mountain so I decided to head back down.

Sadly, having reached the highest peak in the Rockies, my options for setting a new personal elevation record are now somewhat limited unless Warren Buffet unexpectedly names me in his inheritance or I find a big bag of money on the street (those are pretty much the same if you think about it…) and decide to go to Alaska or South America (to make a donation, you can find my contact information on the About page). Or, on a slightly cheaper thought, Mt. Whitney anyone?

14,433 feet!


Obituary for a DSLR

My trusty Nikon D70 died today after nearly 35,000 shutter actuations, in a beautiful place no less; more than 10,000 feet above sea level along the West Fork of the Cimarron River, high in the ice-sculpted pinnacles of the San Juan Mountains of southwestern Colorado. Given that it had pluckily survived numerous 5+ foot drops onto hard, rocky surfaces, many torrential downpours, hitchhiking across the sheep-filled land known as New Zealand, and being partially submerged in mineral-rich water as I uncontrollably floated down Havasu Creek, it seems odd that a light bump against a ratty-looking old lodgepole pine is what ultimately brought it to what in hindsight seems a rather ignominious end. Alas, this accidental tap caused the camera’s shutter to cease operating, casting the camera’s 6.3 megapixel CCD chip into a state of eternal darkness, never again to capture the majestic photons emitted by the incomparable scenery of this great Earth.

The final shot…

Not even the most exquisitely crafted prose can capture the stunning allure of the natural setting in which the D70 ultimately met its demise.  Its final hours were spent summiting the rocky, yet green and verdant slopes of 12,152 foot Courthouse Mountain, a impressive edifice that is but a mere foothill to the soaring 14,000 foot peaks of the San Juan’s above. Despite it’s striking appearance, more than 1200 other peaks in the state of Colorado exceed it in height, although after today’s passing, none will exceed it in sentimental significance. A more glorious and perfect day could nary have been found; the weather gods were beaming upon the landscape below, basking the D70 in warm, unintterupted sunlight as it ascended the mountain, strapped to the shoulders of its loving owner.

The last photo with a human being in it…

From the summit, the D70 faithfully recorded its final panorama; a wide swath that included the jagged crags of Dunsinane Mountain and Precipice Peak, the dark green lodgepole stands of the Uncompahgre Wilderness, and the distant summits of Uncompaghre Peak and Mt. Sneffels, gripping tightly to their last vestiges of winter snow. To the north, beyond the exquisitely layered deposits of Chimney Rock belaying its violent volcanic history, lay the verdant Uncompahgre Valley, home to the towns of Ridgway, Montrose, and Delta. Along the eastern base of the mountain lay the valley carved by the West Fork of the Cimarron River, on an arrow straight path north to eventually meet the mighty Gunnison River.

Until such time that a suitable replacement can be procured, the D70 will be replaced by a small, yet capable Canon point-and-shoot camera. In lieu of flowers, please send Amazon.com or B&H Photo gift cards.
