Recreational Observation

We skied on a ridge to the east of an area called the Hour Glass on the Shuksan Arm. The sun affected slopes were easily rigged with ski cuts. They were propigating quite large and running a long way. Definitely life threatening slides. Many other slides also occurred on the arm but I thought people would like to see these. Stay safe this weekend and avoid rapidly warming slopes!

Weather: Fair

Snowpack: 14”+ new on wind slabs and facets from two weeks of high pressure. A variety of densities exist within the new storm snow. Mid storm warming created a slab above light snow on top of facets.

Area Description: Hidden Bowl - Shuksan Arm

Avalanches: Two slides both skier triggered with ski cuts. First slide was top skiers left side of Hidden Bowl. 6”-12” depth, 200 ft wide and ran for 1000 ft. Second slide was lower on skier left side of Hidden Bowl. 12”- 18”, propagated 200 ft and ran for 500 ft
