Mount St. Helens/Worm Flows


Intermediate Snowshoe - Mount St. Helens/Worm Flows

Last chance to snowshoe up Mount St. Helens' classic winter route before the permitting season begins! Rescheduled from Mar 16th.

  • Technical 4, Strenuous 4
  • Challenging
  • Mileage: 10.5 mi
  • Elevation Gain: 5,700 ft
  • Pace: 1.5-2.0 mph

We will meet up at the Marble  Mountain Sno-park at 5 AM on Saturday. Recommend car camping the night before.  We will gear-up, brief, and start down the trail by 5:30.

The expected pace will be 2-2.5 mph on the lower slopes and then 1.0-1.5 mph once the serious climbing beings (roughly 3 miles in). High clearance vehicles are recommended as the road to Marble Mountain Sno-Park is unreliably plowed.

If the group is interested, we could have a destination planned for the other day as well to get in a solid weekend.

Leader Permission Required

Participants must be prepared for the high level of conditioning needed for the climb. Recent trip history should support this. Note that as a Technical 4 snowshoe,  intermediate showshoe students are not allowed on this trip (the website says you are, but this is a problem being addressed).
