These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Burnt trees and melting snow Runnels in the snow surface indicating melt water drainage. Many areas on the S-facing side of the ridge were completely free of snow. Thin melt freeze crust on sunny aspects. This crust melted away quickly as the day warmed up. Forecaster

Looking at the SE facing part of the Corkscrew slide path and it had virtually no previous wet loose activity. Minimal evidence of wind effect below ridges. Ample evidence of wind effect on ridges. Looking up towards the SE cliffs at noon and there was still very little evidence of wet loose activity. Professional Observer

Snowpack Observation 		Deep Creek
Cabin Creek, Deep Creek, or Pole Creek Area 		Thin frozen sun crust in the shade of a tree on a SE aspect @ 7800 ft in the top photo and soft moist snow above cold dry snow in a sunny spot on the same slope. 3 of 7 test pits at various locations between 6300 ft and 8200 ft on N and NE aspects. See text for details. Cornice pieces dropped on a small wind-loaded test slope. They did not trigger any cracks or signs of wind slab instability. Recent sluffs of cold dry snow on steep terrain. Tiny roller-balls were the only signs of wet snow on sunny slopes. Forecaster
