Primary Problem: Wet Snow
Bottom Line: Hazards associated with wet melting snow are the number one concern and they could take many forms. Loose wet slides will easily triggered as soon as the surface gets wet more than a few inches deep. The deeper the wetting gets, the larger these slides could be. The possibility of bigger, deeper, wider, more unpredictable wet slabs is also starting to become a reality. Shady slopes that have stayed dry aren’t entirely immune from avalanche hazard. You may still be able to trigger a wind slab in a wind-loaded pocket or on weak layers in the upper couple feet of the snowpack.

Elevation: 9,800

From obs on 04/05/2024: "Toured into Beehive Basin on 04/05/2024. Light freeze overnight ~0.5" crust with wet snow below on most slopes. Treed areas did not freeze. Clouds along with a cold south wind kept many slopes from softening. By 11:30 sunny slopes below 9000' had become wet and made for poor ski conditions. Attached are photos of recent loose wet avalanches that likely happened 24-48 hours ago. All attached photos on SW-W aspects at ~9800'"

From email: We were out camping around the east side of Sphinx Mountain. We rode sleds over dirt for a while and came from Buck Ridge. We didn’t see any fresh avalanche crowns all weekend. We did get a big whoomph that collapsed the snowpack while skinning along a ridgeline on Sphinx that seemed freshly loaded. Cracks shot out maybe 25 feet around, but it didn’t move. We didn’t dig snow pits; we followed our plan of keeping our terrain selection on the mellow side.

  • An avalanche we either triggered from 750-800 feet away or it broke naturally. This avalanche happened when we were riding near the larger of the two avalanches from yesterday, on the south side of Cedar Mtn. It was a wind-loaded slope, actively loading. The avalanche was ~130' wide with 100' of 4-12" deep new snow/wind slab and 30' wide broke almost 3 feet deep on weak snow near the ground. Photo: GNFAC

  • From BSSP on 2/17/24: "Midafternoon we received another report of a skier triggered avalanche in the Lone Lake Circe, specifically The Mullet. The reporting party contacted several ski patrollers via cell phone and confirmed that nobody was injured or had taken the full ride. This avalanche failed near the ground on a high elevation NW facing slope with the weight of a single skier with an estimated size of HS-ASu-R3-D2.5-O."
