Name: K and K Rohrig
Subject: Buried surface hoar- Coney’s
Aspect: North East
Elevation: 10,800′

Weather: Obscured, sporadic snow with periods of intense snow
Light S winds
Snowpack: Top of Convex Corner on Coney’s, just below the ridge line, < 30 degrees
250 cm HS
5-7 cm new snow
CTM x 2 SP, ECTP14, down 50 cm, failed on 3-5 mm surface hoar
We found another non reactive layer that “propagated” the full 90 cm when we pulled our ECT column into the pit. This is a layer of decomposing graupel down 20 cm. No cracking, no whomphing, no other signs of instability.
