Irwin Snow Obs

CB Avalanche Center 2015-16 Observations

Location: Kebler Pass Area
Date of Observation: 01/07/2016
Name: Irwin Guides
Subject: Irwin Snow Obs
Aspect: North

Weather: Cool temps, goose feathers most the morning, light accumulations, afternoon saw predicted pulse of moisture, 3” of additional very low density snow, heavy at times with low visibility. Only wind was very highest ridgelines, but SW winds were just strong enough to be transporting snow into 4F windslabs 6-12” deep in lee and x-loaded terrain like upper PH left entrance, etc.
Snowpack: 10” new snow as of 1600. Light density, 4% in morning, 3% in afternoon!! Marginal bonding with easterly and southerly suncrusts, stubbornly sluffed if terrain was steep enough (35ΒΊ+). Not significant enough accumulation to change stability, Irwin remains at LOW danger, but stability due to sluffing decreased slightly. With such fluffy snow, expect high settlement rates over next 36hrs. Vis in afternoon allowed limited visibility to Ruby, widespread new snow sluffing.
