A few wet slabs on Gothic from last week’s warmup

Date of Observation: 05/26/2022
Name: Zach Guy

Zone: Southeast Mountains
Route Description: Traveled on N and NE aspects of Gothic Mtn, to 11,900′

Observed avalanche activity: Yes
Avalanches: A couple of large wet slabs on the north side of Gothic ran during last week’s heat wave, along with what looks like a large wet avalanche near Daisy Pass. Also a few wet loose up to D1.5 in Copper Creek.
Traveled over fairly extensive tree damage on a previously undocumented slide presumably from the holiday cycle.
Weather: Sunny, light breeze.
Snowpack: Drainage through the snowpack is well established here, even on northerly aspects. Snow surfaces are old, dusty, and sun-textured, with very thin pockets of white snow from the past storm. Given how mature the surface is, it seems that wet loose concerns are isolated to very steep, rocky slopes. Traveled on a few suspect slopes that were past prime and couldn’t get anything to move, despite shin-deep ski and knee-deep boot pen near shallow rocky areas. Cornices still pose a threat above some slopes.

Wet avalanches

Date of Observation: 05/17/2022
Name: Ben Pritchett

Zone: Southeast Mountains
Route Description: near Crested Butte

Observed avalanche activity: Yes
Avalanches: May 16 and 17 a cycle of wet avalanches ran that are gouging deeper into the snowpack. These started as loose avalanches, some from cornice collapses, with some gouging out narrow slabs breaking near the ground. Four of them grew large in size.
Weather: several near-record warm days with non-freezing nights. May 14th was the last night with a good freeze above treeline. Notably, at the Butte snotel (10,150′) the last solid valley freeze was May 5th.
Snowpack: Snowpack mostly gone at lower elevations. The snowpack is remarkably dirty and only continuous at upper elevations. The high elevations of the Ruby Range and Paradise Divide area still hold much more snow than other areas.
