Drove through Summit Lake around 8pm. A number of very large wet avalanches released recently. When I drove through at 3pm I didn’t notice these, but visibility wasn’t very good. Light rain on/off all day today followed by clearing skis and partly sunny this evening.

Spirit Walker, Butch, and Andy Simmons all had large recent avalanche with large crowns.
