Potosi Peak, 13,786 feet, is at the east end of the Sneffels Range. Its flat summit is unique for the area and stands out when seen among a sea of jagged San Juan peaks. From most vantage points it would appear that skiing from the summit wouldn’t be possible, but somewhat hidden from view is a steep, north-facing couloir, one that is pretty tough to get to, but well worth the trip.
Christy and I first saw the North Couloir when we climbed nearby Teakettle Mountain back in 2004. Even though it was mid-summer, we recognized its potential for skiing. Two years ago when we returned to ski Teakettle as part of our Centennial Ski Project (read here), we caught a good glimpse of the snow-filled couloir, and we decided we had to get back there to ski someday.
Christy, Joey and I went to Potosi last weekend.
Skiing Potosi is a little more complicated than you would expect. The north side of the mountain isn’t practical for a direct approach. Skiers have to start on the south side, high in Yankee Boy Basin, and go up and over a saddle to access the north side and the couloir. Unfortunately for us last weekend, the road was closed four miles below the Yankee Boy TH. The nearby mine has locked the gate (even though it’s plowed) so our day began with a long walk up the Camp Bird Mine Road, skis and boots mounted to our packs. Christy said the added eight roundtrip miles served as good training. You’ve got to love her take on things.
After we reached the usual starting point in Yankee Boy Basin, we began climbing up a prominent gully on the south side. After negotiating an unexpected frozen ice section, we made it up to the 13,100 foot saddle between Coffeepot and Potosi peaks. From the saddle we slipped between a couple of cornices and skied a line to the north for about 500 feet, which put us at the base of the couloir. From there it was about 1200 vertical feet up to a small col, where another snowy ramp wrapped around the back and up to the distinctive flat summit. The return trip required we retrace our route entirely, so we had three climbs and three descents through the day.
We were impressed with the amount of snow the recent storms had deposited in the couloir. It was tiring work on the ascent but it made for really fun skiing. And our timing worked out really well, most of the day was spent in mixed spring weather, but while we were on the summit and then skiing, the clouds were a bit broken up and we actually caught some sun and great views.
Potosi was a long, hard day which made it all the more rewarding to get done. Put it on your list, if it isn’t already.

Very nice conditions, at least in the coolie. We stashed a car down low and skied (and hiked) out the summer trail, negating the need for returning the way we came in which was very soft as it was late in the year. All in all a super line http://www.mountainphotographer.com/potosi/
Nice Ann. Looks like a nice summer trail in June. Out of towners like ourselves had little business wandering down there without knowing the way last weekend. Next time.
What a cool couloir, Ted. I haven’t skied it, but from the looks of it it does look even better than Grizz’s north couloir. Love your pics, too. The mixed spring weather and intermittent clouds make for really neat shots. Nice work, guys.
It’s pretty similar in length to Grizzly’s couloir, but this one is a bit tighter at times. Both fun worth checking out.
Very nice, Ted. Looks like you guys had awesome conditions in there!
That gate/road has been a bummer this year. We were down there a few weeks ago ready to give the Snake a try but elected to hit some other objectives when we learned we’d have to add 8 miles to the day. Seems like they’re getting more anal about it as a few years ago the gate was open in late-April and we had no problem driving all the way to the Governor Basin junction 4 days in a row. Or maybe it’s always been this way and we just got lucky that weekend. Anyway, I’m glad to see it didn’t stop you guys!
G’luck in the Weminuche if you head in there and thanks for the book link 🙂
Thx Ben. Interesting to hear. One mine employee actually apologized as he drove by saying the road should be open. I guess the mine just doesn’t want to have to deal w helping stuck cars during the winter.
