Bitterroot Beta

A free guidebook to Bouldering in Western Montana's Lost Horse Canyon and Bitterroot Valley.

News: The Western Montana Climbers Coalition is brining back the Lost Horse Climbers Festival!

This started as notes on a few new problems and has grown into an ongoing attempt to produce a somewhat up to date guide to the impeccable bouldering in Lost Horse Canyon.

A rough draft is available here:

Lost Horse Bouldering v0.7 (PDF updated 9/14/2018)

Please submit corrections, additions and ratings suggestions to or via facebook.

The guide includes 300+ problem in the lower canyon (below the south fork) and some information on the area and local amenities. A guide covering the upper canyon is in the works.

The book is 80+ pages long and still being updated. To save paper, you can save a copy to your phone or print it with two pages per sheet as a booklet if your printer supports that.

The guide is free but if you like it consider supporting The Access Fund and Western Montana Climbers Coalition.

Jim Striebel and Eric Chesebro have provided a copy of the guide they wrote in 1994 for the first Lost Horse climbing competition:
