Location: Kebler Pass Area
Date of Observation: 02/06/2020
Name: Ian Havlick
Subject: Irwin Tenure Obs
Aspect: East, South East, South, South West, West
Elevation: 10-12,000
Avalanches: (2) SS-AS-R2-D1.5-I 2ft windslabs failing above 2/4 MFcr. 1F dense slab, east facing terrain NTL. Failed pretty early in storm, around 10am. Otherwise, lots of storm slabs all day, growing in size and tenderness late in day. Steep features were sluffing and cracking and running naturally around 1600.

Weather: 2″ 10% density snowfall as of 0800, snow intensified 0930, and stayed pinned at nuking rest of day, west winds were sporadic, also variable at ridgetop (12K).

Snowpack: dense snow transitioned to uber fluff, 7″ .2 SWE by 1600, though it felt and skied much deeper. Small scale local winds patterns were unusually eddying around blowing east, reverse loading interesting places. Wind drifts were unusually fluffy and low density, easily able to ski through waist deep drifts. Snow seemed to be growing in density at sunset
