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 		Mt Houghton
Mount Rose Area 		Lots of bare ground showing on a SW aspect at 8700 ft. The snow remained supportable on N aspects until my departure around 2 pm. Southerly aspects on Mt Rose are almost completely snow free. Areas of deep and unsupportable wet snow started to exist on E aspects by 1 pm. Snow continues to melt on SE aspects above 9500 ft on Mt Houghton. The corridors of snow in the gullies are getting narrower. N, NE, and E aspects still have decent coverage on Relay Peak. Forecaster
