Avalanche Details

Cornice Fall on West Face of Pyramid. This looks to have triggered at least one shallow slab avalanche - crown can be seen on lookers right just under section of cornice still intact. Debris ran around 2,000' to the alders.

Slab avalanche on the West Facing ridgeline of the West Ridge of Explorer Glacier. Likely a heavily wind loaded slope from the storm snow over the weekend and strong Easterly winds in this area.

Photos of both these below. Both these slides likely ran on Sunday, 3/29 or early Monday, 3/30.
