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
Talking Mt.

Echo Summit Area
This small mound on the approach ridge held very soft surface snow on the shady aspects but a thin breakable crust on the solar aspects. Beneath the crust similar very soft snow (NSFs) was present. Stomping on small cornices on the ridge produced small breaks that didn't produce much excitement. In more open areas some wind slab was present. This was sitting on top of 20cms of very soft snow. The wind slab was very easy to remove and expose the soft SH and NSFs below. Despite a small wind slab, ECTs did not produce propagation. Ski cuts on small test features also did not produce results in this area. Professional Observer
