Lost River Range Rock Climbing
The Lost River Range
The Lost River Range is Idaho's tallest. It contains 7 of the 9 12ers in Idaho, including Idaho's highest peak, Mt. Borah.
While the range may be known for loose, chossy rock, there are certainly exceptions to this rule. There are also many alpine ice routes that form up every year, and a massive potential for ski mountaineering.
The range runs north to south. Highway 93 runs along the west side of the range between Arco and Challis. Because of this, access to routes from the west side is fairly straightforward.
The east side, however, is much more difficult to get to. For routes originating on the east side, turn east off of highway 93 onto Doublespring Pass road, about a mile north of the Mount Borah trailhead turnoff. Proceed over Doublespring Pass and then navigate the maze of backroads to your trailhead. These roads are very rugged and a high clearance vehicle is mandatory.

The route difficulty depends a lot on the conditions. The first ascent was put up in September, when it sounds like the ice was snot thin, and there was a lot of rock climbing on dubious stone. We did the route at the end of May, and found copious amounts of snow and fat ice, although we did still have to climb some ro...[more] Browse More Classics in ID
