Description 

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.

Getting There 

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.

North Face of Mount Borah AI3 Mod. Snow  ID : Lost River Range : Mt. Borah
The north face of Mount Borah is an Idaho classic! It is a huge and imposing face that looks like it belongs in the Canadian Rockies.Although this route can be done as a snow climb in the early summer once the avalanche danger has subsided, it is best to wait until early fall when the route becomes pitch upon pitch of beautiful alpine ice. The number of pitches of ice will vary depending on conditions, and how high up the snow you have to climb to get to the start of the ice.After climbing the...[more]   Browse More Classics in ID
