Description of Snow, Weather, and Avalanche Conditions:

Saw a small, obvious slide right off the highway around mile 19.5 on I-580 just west of the highway. It was a steep ravine with little vegetation and a slope pushing 40 degrees. Looked like a wind-loaded slab near the top of the ravine with a 1ft crown (all measurements estimated from a distance). There's an unpleasant terrain trap at the bottom of the ravine not sure if it ran the full slope though.
