CB Avalanche Center2016-17 Observations

Location: Kebler Pass Area
Date of Observation: 01/13/2017
Name: Zach Guy
Subject: Irwin obs
Aspect: South East
Elevation: 11,800 ft

Avalanches: Skier triggered and explosive triggered about 5 soft slabs, up to 18″ thick, behind cross loaded features, failing on mid storm layers. Flat light and limited visibility of surrounding range. Could see one D2 crown off of E aspect of Ruby Peak and one debris pile below Ruby that ran fairly far, now smoothed over by wind. Maybe R3 or so.
Weather: S-1. Mostly overcast. High of 31. Light winds with minimal transport
Snowpack: 6″ new this morning, with some drifting from southerly winds. Above treeline: intense winds during the last storm have left some alpine slopes scoured to rock, and obvious variability in snow depth depending on crossloading and aspect.
