Starting with May 1 climbs, Climb Registration Fee includes Mt. St. Helens Permit Fee ($22/person).
This route is open year round from the Marble Mountain Snow Park, so it's usually used for early season ascents. It's about 1,000 more vertical feet than Monitor ridge. Snow can be soft early season due to the low starting elevation, so bring skis or snowshoes in case. St. Helens is one of the lower and technically easier glaciated peaks in the Pacific NW, but still a strenuous climb as the starting elevation is relatively low. The peak is often underestimated; exposure and route finding challenges in low visibility can make this peak a serious as any in the Northwest. Watch out for the cornices on the summit crater!
This is a classic NW ski climb, with long open runs, minimal avy danger, and no crevasses. This can be a nice overnight trip as well - ski in, make camp, and hike up for some tele turns. Permits and Stuff: St Helens is one of the most heavily regulated peaks in the US. See the Gifford Pinchot National Forest web site for current permit regulations, SnoPark permit required between Nov 15 and April 30.
