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.

Snowpack Observation 		Stevens Peak
Carson Pass Area 		Easy cracking in small lower elevation windslabs Test results limited to upper portion of snowpack with CT13s and ECTN 17s just below wind hardened snow. Poking around on north facing slopes near top of Stevens found some areas with large rounding facets. Professional Observer

Snowpack Observation 		Becker Ridge
Echo Summit Area 		Only 1-2 cms of new snow in protected clearing. In wind loaded area more snow was present. In very small wind loaded areas, some drifts were showing signs of cohesion. Impressive wind transported snow on Stevens and Red Lake Peak in the distance. Overview of ridge conditions (from R to L): scoured surfaced on bottom right, then some new snow showing signs of erosion, then wind deposited snow.
