We rode to Round Lake and around the north and west side of Sheep, and back out through Round Lake. There was a big avalanche on the northeast side of Sheep that was previously not reported. It was there this morning so maybe happened yesterday. 6-8'+ deep, 500' wide R4-D3-O.

This morning we saw previous avalanches on Henderson Mtn. in better light and got a photo of one on the lower Henderson Bench. Showing wide propagation through thick trees.

Temps were warm under clear skies with calm wind. Snow surface was getting moist in the afternoon on sunny slopes.
