We had an interesting low angle tour today, triggering several soft slab avalanches throughout the day. The most impressive was thi

Comments

The slide ran into the trees and left enough hangfire that no one volunteered to measure the start zone angle, though it appeared to be in the mid-30s

Comments

Later in the day, we watched this lone skier edge out into No Name where he triggered this soft slab. The avalanche initiated below him and propagated along the ridgeline to the left edge of the photo. The slope from the skier to the summit and onward to where the photo was taken had avalanched sometime during the storm, with the crown partially buried by last night's snow.

Comments

This avalanche ran perhaps 3/4 path, with the toe of the debris out of the frame. Moments after taking this photo I remotely triggered yet another soft slab, similar in depth to the others, as I skied along the ridgeline. Like the others, it propagated several hundred feet wide, entraining what appeared to be just about all of th un-avalanched new snow in the upper part of the drainage.
