CB Avalanche Center 2018-19 Observations

Location: Kebler Pass Area
Date of Observation: 02/07/2019
Name: Eleven Cat Ski Guides

Subject: Irwin Cat Obs
Aspect: East, South East, South, South West, West
Elevation: 10-12,000ft


Only a few minor results from ski cuts pulling out storm slabs in Way Long & R2 below
Sunset. Overall Storm slab/wind slab was stubborn to ski cuts, but reactive to Size 1s with explosives. No
visibility to observe surrounding terrain.

Weather: Unable to gain access to ridge cat drops; extreme winds, low visibility and wind chill
values shut us down! Cold day with strong to extreme gusts and temps intensifying around 11:00 throughout
the remainder of day. Skies went to BRK at 1630.

Snowpack: Morning started out similar to yesterday, but as winds increased the storm slab
stiffened dramatically through the day. Ski quality was stiff cream cheese with wind slabs lower on slope
that would stuff the relaxed, laid back skiers. Protected terrain held the most quality. We are now riding
the slab and skier penetration is decreasing dramatically.
