Date of Observation: 01/09/2016
Name: Dave and Krista
Subject: Avy 1 Obs
Aspect: North East
Elevation: 9,600 – 10,8000

Avalanches:
Weather: High around 20F small period of S-1. Overcast sky most of the day. Light winds from the N/NE, partly cloudy with a few snow squalls and a nice sunny period in the afternoon.
Snowpack: Ob#1: HS averaged 80-90cm. We dug 2 pits, 28/32* slopes and did several CT’s. We had consistent results: CTH (21/22) with most releasing at and just above the DH layer on the ground. One result released 10 cm just above the DH layer (30 cm from the ground) with a SC. We had 1F hardness in our mid pack which made for very supportive skiing.
Ob#1: HS ranges from 75-88 cm. In our pit we got moderate results on CT tests releasing on the
DH layer (2-3 cm) on the ground. Got no results on ECT test. Still a 4F harness soft slab but it is faceting out. Pit was on a NE aspect on a 26 degree slope.
