A group remotely triggered a wet slab avalanche from the ridge top. There were shooting cracks that connected their location to the avalanche. This is an interesting of persistent weak layer and wet snow avalanche problems. Photo: M Harry

L-AS
Coordinates: 45.3477, -111.3890
Caught: 0 ; Buried: 0
From obs: "We saw several loose avalanches on WSW, ESE & SSE aspects of the ridge between beehive and bear basin. The one on the ESE slope may have been skier triggered (by another group) and the rest appeared to be natural. We found a strong crust beneath the foot of new snow throughout our route. We didn't see any cracks or whumphs, and the new snow wasn't reactive in hand pits. The snow surface was getting wet as we exited to the beehive trailhead around 3pm."

On 2/18/24 near Buck Ridge and Muddy Creek we saw at least eight recent avalanches that occurred at various times over the last 1-3 days, natural and/or remote triggered by riders. A group in the parking lot mentioned seeing many slides actively happen in this area on Friday 2/16. Most were 2-3' deep hard slabs, ranging from 50'-500' wide. Photo: GNFAC

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."

The Last Word
We began our daily forecasts on December 7. 130 daily forecasts and 464 reported avalanches later, we wrapped up our daily forecasting season on April 14th. While avalanches remain a concern until the snow is in the rivers, read our SEASON SUMMARY to look back at the heart of the 2023-24 avalanche year.
