"Toured into Frazier Basin today [4/1/23] and noted a few instabilities.... Second, we saw a large natural avalanche above Ainger lake (E-SE facing) that ran from near the top of the ridge itself to propelling debris up, over, and past the lake. The crown ranged from 2-5ft high spanning 400-500ft across the face."
"Saw this crown from a distance today [4/1/23]. Possibly natural R3-D3 on ESE aspect, likely caused by wind loading. Unsure when it occurred, but crown looked large and debris ran into the flats mowing down some small flag trees."
