Mount St. Helens/Worm Flows


Intermediate Snowshoe - Mount St. Helens/Worm Flows

CANCELED due to CoViD-19 response. Backup date for the trip planned on the 21st. If that is successful, this will be a snowshoe trip to Mount Catherine (or equivalent).

COVID-19: Learn about our most up-to-date guidance for participants and leaders on our COVID-19 Response page. All participants and leaders must agree to the COVID-19 Code of Conduct before participating in this Mountaineers activity.
  • Very Strenuous
  • Challenging
  • Mileage: 12.0 mi
  • Elevation Gain: 5,700 ft
  • Pace: 1.5-2.0mph

Marble Mountain Sno-park @ 5AM. Car camping the night before recommended. Sno-park (non-groomed) pass required.

Leader Permission Required

This is a backup in case the  March 21st trip doesn't go. If that trip to St. Helens is successful, this will be converted to an alternate intermediate snowshoe (likely Mount Catherine or something similar). Please do not request permission if you are not okay with that.

Finally, the distance, gain, and pace are such that leader permission is appropriate. You should be doing winter conditioning with similar distance and at least 3k feet of gain.
