Northern Gallatin

From (5/17/20): "...WS - ASu - R3 - D2 - I SE face of Middle Basin Peak starting at 10,000' Estimated SZ of 30° Slab depth of about 8". We were out too late in the day and chose to ignore a number of observational warnings. We were lucky and remotely triggered the avalanche below us."

From obs: "Here are a few snaps from yesterday (5/2/20), looking into the Absaroka from up on Emigrant. Fair bit of smaller, pockety wet slab activity in steep, rocky terrain near the middle/upper transition. I didn't see anything larger than D2 or any activity in true upper elevation terrain."

Avalanche Details: Many wet slides in Absaroka

From obs (5/3/20): "N facing gulley, probably similar results from the Pine Creek avalanche posted on 4/29. Avalanche appears to be natural and possibly a couple days old. Ran about 400’ wide in the cone and damned up the creek with massive cement-like debris. There were more similar avalanches on N facing aspects the more I traveled. The skinning was isothermic and sloppy as each step fell through the snowpack to the ground"
