The Spectacular San Juans: A Trip to Yankee Boy Basin

Taking in the scenery

Note: I’m reaching back into the archives here. I have about 10 posts in my drafts folder, all in various stages of completion and many from this past summer, that I’ve decided it’s finally time to post. This is one of them. And yes I know this is my 2nd consecutive post with glacial and geological undertones. I’m not sorry, glaciers are totally radical man!

On my lifetime list of most spectacular landscapes, Yankee Boy Basin in the San Juan Mountains ranks quite high. I’ve seen expansive fields of wildflowers with different species spanning every color of the rainbow plus some. I’ve seen 100 foot high waterfalls that have undoubtedly been the setting for numerous Coors commercials. I’ve seen craggy, majestic mountain peaks and pinnacles sculpted over millions of years by the work of a posse of many abrasive glaciers. I’ve seen aqua blue lakes appear seemingly out of nowhere as they fill from the meltwater of a lobate rock glacier. I’ve seen ribbons of crystal clear snow melt water plunging in an endless stream of cascades straight down the side of a mile wide glacier cirque. Never though have I seen all these things in one place. Yankee Boy Basin truly has it all. It rivals anything I ever saw in the mountains of New Zealand. Throw in the fact that I saw up-close and in person just about every glacial and periglacial feature I learned about in geomorphology class and it doesn’t get much better. Miraculously, you can actually get here with minimal effort, especially if you have a 4WD vehicle (or, in our case, the ability to rent one), and don’t mind driving on roads that look like this:

Mind you, merely walking around on a level surface at nearly 13,000 feet involves a fair bit of effort and energy expenditure.  Altitude acclimatization definitely makes things easier but even then, running around in excitement is definitely not recommended since I imagine the scenery would not be as greatly appreciated if you are passed out on the floor of the basin. Amazingly, over 1500 individuals each year blatantly ignore this advice during an annual 17 mile footrace up and over nearby 13,114′ Imogene Pass.  In an additional twist that can only be explained as a classic example of male one-up-manship, in the early 1990’s, some folks decided that running 17 miles at extremely high altitude was not torturous enough and thus the Hardrock 100 was born.  Participants in this masochistic race traverse 100 miles of rough terrain at an AVERAGE elevation of over 11,000 feet, climbing up the passes and peaks in the vicinity of Yankee Boy Basin.  The total elevation gained and lost during the race is a mind-boggling 67,984 feet. Yeah, altitude does crazy things to people.

Trail headed up to Wright’s Lake

One of the neatest features of Yankee Boy Basin is a 50 yard wide body of water called Wright’s Lake.  Wright’s Lake is bounded on the east by a terminal glacial moraine which forms a small ridge meaning that the lake does not come into view until you are practically wading into it. I had not seen any pictures of the lake prior to the hike so I was unsure what to expect. After smoking my little brother up the short trail from the road, I came around the edge of the moraine to see an enormous rock glacier flowing down from Gilpin Peak 1000 feet above me and terminating at the edge of an aquamarine blue lake, a sight which exceeded even my most hopeful expectations. The sight of a lake sourcing a not-insignificantly sized stream with no immediately obvious source of replenishment is an odd one indeed until you realize that the wall of talus on the far side of the lake is cored with ice.

Rock glaciers are interesting beasts. They are essentially glaciers covered with a layer of rock that serves to insulates the ice which continues to flow downslope under the influence of gravity. To completely cover a glacier in rock, one naturally needs a lot of rock. The peaks in the San Juans generally consist of extremely crumbly, scuzzy volcanic tuff and ash deposits. Gilpin Peak, the summit from which the rock glacier descends, is no exception as it looks like the whole mountain could slough off into the valley during the next stiff breeze. Debris from the peak above the glacier falls from the sheer cliffs ringing the basin and accumulates on the surface of the ice. The insulating effect of the rock has allows these small remnants of ice (the San Juans were home to much more extensive glaciers during the most recent glacial period) to survive here even though the current climate in the San Juan’s is too warm and dry for traditional glaciers to survive.

From Wright’s Lake, it is about 1.5 miles and another 1500 feet up to the summit of Mt. Sneffels, one of Colorado’s famous 14ers (peaks over 14,000 feet high) and one that is not on anyone’s list of “easiest to climb”. On this day, the notoriously nasty conditions on the summit of Sneffels was apparently even from a quarter mile below. From the lake you could easily hear the wind whipping around on the summit ridge and thunderstorms were approaching from the west.

As I finally get around to finishing this post in early January, I am struck by the thought of how this amazing landscape is now buried under many, many feet of snow. While I am sure that the San Juan’s are equally inspiring in the winter, perhaps even more so to many people, thinking about this gives me an even greater appreciation for such places, given just how short of a window we have each year to experience alpine landscapes such as this one. The winter of 2011-2012 was an incredibly dry one in Colorado, and many places such as Yankee Boy Basin were mostly snow-free and accessible by May or June. In a normal snowfall year, vehicle access to these high altitude basins is often impossible well into July or even August, leaving potentially as little as 6 weeks before next winter’s snows begin to reclaim the land once again.

Where the Rivers Run Orange: Remnants of a Colorado Silver Rush

The San Juan Mountains have a way of making you feel uneasy.  Perhaps this has something to do with the fact that the most infamous cannibal of our time, one Alferd Packer, consumed five of his fellow prospectors here during the winter of 1873-1874. But while the alpine scenery rivals or exceeds that of any mountain range I’ve ever visited, the fact that many of the streams cascading down the steep slopes run with a neon, metallic orange color that coats every last pebble along the streambed in a golden veneer lets you know that something is wrong.

A very orange and acidic Red Mountain Creek

While you might think that someone dumped a truckload of kool-aid into the mountains, in reality it’s because the San Juan’s used to be gold and silver country. Looking at a topographic map of the San Juan’s is like looking at some sort of twisted and tortuous treasure map, with literally thousands upon thousands of tiny crosses marking the locations of long defunct mine shafts, many of them waiting to swallow up the unaware hiker.  The majority of these mines were established in the later 1800’s when silver in previously unheard of concentrations was discovered in the mountains, along with smaller amounts of gold, zinc, copper, and other heavy metals. Like an enormous hardrock gopher mound, the San Juan’s are riddled with underground mining tunnels. It is possible to travel between the towns of Silverton and Telluride, several hours apart by road, without ever setting foot on the surface of the Earth.  While few active mines still exist, the imprint that the mining had on the land is readily apparent to anyone traveling between Ouray and Silverton on U.S. Highway 550, commonly known as the Million Dollar Highway (for reasons which are disputed…) which, due to the persistent lack of guardrails along its more perilous stretches, is not for the faint of heart.

Ouray County Road 31 branches off of Hwy 550 about halfway between Ouray and Silverton and winds through the Red Mountain Mining District for several miles. This area, located about 10,000 feet above sea level, was home to a number of rowdy mining towns during the its heyday in the 1800’s. Since I am rarely (ok, never) mistaken for a history buff, an excellent history of the Red Mountain District written by people who know what they are talking about more than I do can be found here. The road is marked as a 4WD on maps road but seemed very well maintained. I ventured that I could have gotten my trusty Toyota Corolla down it when dry, but probably not at a rate much faster than I could walk it. As a result, I parked my car along the highway and struck out on foot. In hindsight this was both a good and a bad idea. Bad in that the skies of Colorado decided to unleash their first drops of moisture in months, when naturally I had left my rainjacket at home. Thankfully, old mine buildings make for decent shelter if you can find one that doesn’t look like it will collapse in the slightest gust of wind. However this was good considering that the road basically turned into a clay bog as soon as it started raining which means that I would have been S.O.L had I decided to drive instead of walk.

Acid mine drainage along a creek near Red Mountain

A short walk in along Road 31 and it becomes immediately apparent that the land has been completely and utterly gutted by the silver mining process. It is the bright orange creeks and streams catch your eye first. This phenomenon is known as acid mine drainage, and occurs when rainwater or snowmelt comes into contact with metal-rich rocks, such as the rock that composes the tailings piles that surround all of the old mines. The water leaches metals, most commonly iron, out of the rock and into to the water. The iron then oxidizes resulting in the highly acidic, bright orange water that flows throughout the region. Perhaps even more pervasive than the orange creeks though is the smell. Nearly all of the mines and tailings piles are accompanied by a metallic, musty odor that leaves you with the funny feeling that it would probably be a bad life decision to inhale the air for an extended period of time. The smell is truly difficult to describe, the closest analogy I can think of is the hydrogen sulfide so commonly associated with the geysers and hot springs of Yellowstone, although this still falls short. This smell was much less sulfurous and disagreeable, and while I wouldn’t go as far as to say it was pleasant, it wasn’t bad enough to make me cover my airways with a bandanna or seek refuge somewhere else.

Stop number two for the day was the remains of another 19th century mining camp: Ironton. Unlike the Red Mountain District, which was so extensively mined that it is essentially located on a barren hillside that has been mostly stripped of trees, Ironton and its associated mines, such as the Colorado Boy seen below, are nestled deeper within the forest. A well marked trail leads to Colorado Boy but many of the other sites in the area are located along routes that have been nearly completely reclaimed by the forest, making them difficult to find without a good map and good sense of direction since GPS devices don’t work worth a darn in the dense woods.

Just south of Ironton, spanning a large gully known as Corkscrew Gulch, lies a bridge that I am convinced was the inspiration for the rickety wooden span in Shrek that Donkey and Shrek traverse in order to cross the boiling lake of lava.  Oddly, this interesting relic isn’t listed on any maps of the area and I was unable to find many pictures of it online, yet it was one of the highlights of the day. I initially spotted the  bridge from below, it wasn’t even obvious that it was a bridge at first but being the curious cat that I am, I was naturally intrigued. After about a half hour of bushwhacking my way up the ridge on the west side of the gulch, I located the trace of an old, overgrown wagon road that eventually led me to the edge of the canyon and the bridge abutments. Now this bridge, missing as many planks as it was, would have been completely impassable regardless but for whatever reason, one of the two cables spanning the gulch had been cut causing the span of the bridge to hang like a limp wet noodle across the canyon. The bridge is in such bad shape that the weight of a house fly alighting on the remaining cable would likely cause the remainder of the structure to plummet several hundred feet to the streambed below. Interestingly, upon further research, this bridge was at one point the longest suspension bridge in Colorado. To this day, it holds the unofficial title of “sketchiest bridge in Colorado” and I don’t envision it relinquishing this title any time soon.

Despite the glaring environmental ramifications and water quality issues associated with the mining that took place here, , spending an afternoon exploring the mines was a fascinating step back into the exciting history of the San Juan Mountains and southwestern Colorado. The mines are so prevalent and such a seemingly integral part of the landscape here that it is sort of difficult to imagine the San Juan’s without them. Just don’t drink the water….
