Avalanche Details

Pretty much every slop had a crown on the top. Didn't matter what aspect. Every gully near treeline had debris.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Sunny and very warm. Zipper thermometer read 55 degrees.

Snow surface

Wet, dense snow. More like Southeast. Great for building a jump, lousy for landing.
Too bad this doesn't happen in November to lay all those alders down.
Upper areas had wind effect in spots. Every upper valley had avalanche debris. And every upper slope had a crown.
No where near 50" new snow here. Currently settled to maybe 16".


Dug a two pits. Lower one on the near the top of the steeper bowls. Total snow about four feet. Top foot heavy snow. Then obvious crust. Below that a foot of consolidated wet snow. Then another crust. Then a fairly packable snow layer about a foot. Then a crust and lastly maybe a foot of sugar above the ground. Did an ETC and nothing moved. Full sledgehammer only packed the column. No stratification. Prying on the column did release on the second crust, but didn't fully break free, just kind of resettled.
Dug a second pit in the upper flats. Same layers only less snow, and upper new snow layer more wind effected.
