Mount St. Helens Climbing Update
[Last Updated: 14 January 2009]
Fall / Winter Climbing Access: Snowfall and wind will form unstable cornices (snow overhangs) on the crater rim (please see our climbing page and scroll down to cornice photo). The crater rim is unstable and can be hazardous at any time.
Attention Climbers: Winter access to south side climbing routes may be limited by road damage, snow or malfunctioning plow equipment.
