Location: Crested Butte Area
Date of Observation: 12/26/2015
Name: Ian Havlick
Subject: White Mountain Obs
Aspect: South, South West, West
Elevation: 9000-12000

Avalanches: Evidence of avalanches, but generally snowed and drifted in. Avalanche cycle was widespread, and if wind loading continues could see another round of avalanches. We quite worried about remote triggering potential all day, and didnt travel in terrain much steeper than 28º all day.
Weather: Clear skies, cold temps (12ºF), strong radiation and SE-E-NE-N winds in the progession as the day went on.
Snowpack: Thunderous collapses constantly all day, some violent and rattling twigs of snow. 8-10″ settlement cones, active light the moderate snow transport from the E-NE. Shooting cracks ~50ft, but rumbling collapses went much further. 2, ECT tests produced propagating results from 17 and 22 taps, sudden collapse
