Date of Observation: 04/15/2017
Name: Evan Ross
Avalanches: Some very small and slow running loose wet avalanches on slopes over 40 degrees in steepness.
Weather: Big and blue. Light westerly winds at ridgeline.
Snowpack: At 12,500ft the upper snowpack was made up of several crusts merged together to form last nights freeze down to 25cms. Percolation Columns extended below this depth into 4F- melt forms to an observed depth of 40cms.
Boot pen was about 10 to 15cms at 11am with some punching through the upper crust. Current high temperatures and solar gain plus light alpine winds didn’t allow snow surfaces to weaken beyond this at upper elevations. While lower elevations traveled, were much further along in the spring transition and stayed supportable through the end of our day at 2pm.
