West Slopes South - South of I-90 to Columbia River
March 15, 2015, 3:30 p.m. PST
Weather: Snow in the morning turned to rain-snow mix and finally to rain around 1300hrs. Winds were moderate out of the SW.
Snowpack: New snow accumulation of 6-12" was very dependent on elevation. Sticky wet heavy surface snow produce lots of new roller balls on a variety of aspects near treeline. All observation suggest Loose Wet avalanche were possible/likely.
Area Description: We traveled in the Edith Creek area below the Golden Gate bowls and Panorama Point.
Avalanches: We saw 3 Loose Wet avalanches S-SE aspect near treeline. At least two of three were human triggered. The largest was a D2. We also observed one small (D1) storm slab avalanche triggered by a small cornice collapse on a SE aspect NTL below Panorama Face. This appears to have occurred in the early morning hours.
