General Comments

I was touring up to Lake Blanche today when I came upon the aftermath of this monster slide just before reaching the lakes. The snow in the debris pile did not look affected by either rain or snow, so my guess is that it ran either late last night or earlier during the day. Looked like it ran all the way to the ground over much of the track. Scrambling through the debris was like traversing a mini-glacier. The toe was 15-20' high.
