Avy cycle obs as viewed from Snodgrass

Location: Crested Butte Area
Date of Observation: 12/18/2016
Name: Zach Guy
Subject: Avy cycle obs as viewed from Snodgrass
Aspect: South West
Elevation: 9600-11000

Avalanches: See photos. Plenty of evidence of widespread natural avalanche cycle that ended Saturday morning. The most widespread activity was above treeline on leeward or crossloaded slopes, ranging from D2 to D3 in size. Most of the “frequent flyers” below treeline (Happy Chutes, Gibson Ridge, Meridian Lake, etc) held tight except for smaller storm slab action.
Weather: Cold, clear, calm.
Snowpack: 40 cm of F+ storm snow below treeline on SW aspect, on a thin crust. Easy, propagating test results on a mid-storm density difference. We got a few minor collapses while breaking trail below treeline, and one large collapse as we reached more of a near treeline elevation at ~11,000 ft.
