From ob on 02/17/2024: "From woody ridge, we observed a large avalanche across the republic creek drainage (not sure what the peak is called but see the coordinates). I heard it first since it sounded like thunder or a plane, and then saw a huge cloud of snow moving down the mountain across the drainage.  We do not know if it was natural or triggered by someone."

A skier on 02/18/2024 saw a large natural avalanche on the NE face south of Flanders that likely happened on 02/15/2024. Photo: Anonymous 

From email on 02/18/2024: "Photo natural avalanche on a NW aspect at 9000', taken north of Cooke City today. It likely happened right around Feb. 15th."

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."

From FB 02/17/24: "Observed runout debris from a small avalanche on a south facing forested slope in Upper Tepee Basin. Shows avalanches can occur through forested areas." Photo: C. Sexton

From obs 2/17/24: "Lots of natural activity up buck ridge. The one photoed looked like it popped off this morning. Most activity we saw seemed to be on northern facing aspects" Photo: M. Forbes

From email: "We noticed a multitude of slides on north- and east-facing slopes, many of which seemed to have been from the prior weekend. I snapped a picture of one on the opposite side of the drainage that was a couple of feet deep. Adjacent to it was some more debris."
