Zone or Region:
Hidden Lake Area
Did you observe any avalanches? Yes
Size 2: Could bury, injure, or kill a person
Ascending the drainage to access Hidden Lake Peaks there were a number of natural wet slides that let loose on South and South West aspect when the sun came out and started to warm them in the afternoon. They ran about 100 meters, got to be about 10 meters in width.
Solar radiation was the issue. Wet slides had trigger points that went down to the rock in some instances. In addition to the wet slides, N and NW aspects had some wind loading, but didn't end up being a problem.
