Climbing Conditions - Boston Basin Area
Conditions for climbs in the Boston Basin area, including Forbidden, Sharkfin, and Sahale via the Quien Sabe Glacier can be found below. For conditions on other climbs, return to Planning a Climb.
Condition reports come from climbing and wilderness rangers, the voluntary climbing register, and other climbers. To make a climbing report, please email the Wilderness Information Center in Marblemount. Please include the route, snow level, any hazards encountered (or not), peak(s) attempted, and whether your party successfully summitted.
All of the climbing routes in the park complex are located in wilderness, but some are wilder than others, and there may be limited or outdated information. Use these reports as a baseline, but plan for changing conditions and a true adventure. On many routes, the discovery, physical stress, and route-finding challenges are half the fun.
