Toured from twin lakes towards the twin peaks area on 3/19. Noticed this natural avalanche on an NW aspect that went during the storm.
We also had a rider trigger a slide on a steep E facing slope at approx 12,000 ft. in the same area. The rider was able to avoid the avalanche runout and no one was burried or caught. The terrain was a steep and rocky gully with a rather shallow snowpack. 2 others skiied slightly different areas on this same slope previous to this rider. Crown was estimated to be about 10-15' wide, 8" deep, and ran close to 1000'. R2-D1.5. See attached video and photo.
Great ski access to and from the car at Twin Lakes, no walking on dry ground was necessary thankfully! Great coverage in the area.
Mostly sunny day with some clouds developing in the afternoon.
