Wind slabs

Location: Crested Butte Area
Date of Observation: 02/20/2017
Name: Evan Ross, Chris Martin
Subject: Windslabs
Aspect: North East
Elevation: 9,600ft-10,800ft

Avalanches: Small windslab NE aspect Schuylkill Ridge. Small windslab E aspect above Purple Palace. Large windslab E aspect Purple Mountain.
BTL wide propagating slab N aspect Mount Emmons.
Weather: Partly cloudy. Calm winds.
Snowpack: At ridgeline windslabs were about 20cm’s deep over SH and well developed NSF. These slabs were confined to right at the rigeline and small in size. Below ridgeline the slab thinned until it was the last 24 hours of new snow at about 6-8cm. Digging around at 10,200ft and lower, the new snow was only over well developed NSF without the SH. The new snow below 10,200 was becoming heavy from warm temps and sun.
