From e-mail 11/4/21: "Hiking up in the Bridger Range from Sacagawea Pass and noticed no faceting of the current snowpack. The snow near the pass and on the ridge is very wind affected as is to be expected and dropping into the bowl on the east side of the Pass the snowpack there has a distinct sun crust. Dug around a little bit at 8600 ft on a NE aspect and found a sun crust of about two inches with what felt like rounded grains below that. Even in the direct sun, the crust was taking a long time to rewarm and was pretty slippery..." Photo: H. Darby
From obs: 5/9/21: "Yesterday we went to check out the new snow in Beehive Basin.... While traversing... along the north ridge of 10602, we triggered a small wind slab that carried down into Peruvian, which then released another small wind slab on a northeast aspect of the face (photo). The crown height of this wind slab was measured at 60cm at it's deepest point, and approximately 30ft wide by 10ft long.
Looking down into the face of Peruvian, we observed a natural dry loose slide that released from the ridge. We observed an increase in wind speed throughout the morning, and a shift in wind direction from west to southwest in the early morning moving to west to north west by the late morning."

We observed an increase in wind speed throughout the morning, and a shift in wind direction from west to southwest in the early morning moving to west to north west by the late morning. The combination of variable and high winds with the amount of new snow available for transport created a noticeable increase in the hazard of wind slabs on all aspects we observed during the morning..."

Multiple wet slides were reported in southern Madison and Tobacco Roots over the week 5/3-5/7.

From email 5/2/21: "Small but plentiful wet snow avalanches in Cooke City today. Didn’t see any that were broke on a deeper scale."
From obs 4/30/21: "Yesterday I witnessed a big wet slide. It started on the exit from The Fin on Old Man Rays. Looks like it started on a rock band. Noon. Since people have been skiing The Fin recently I just happened to be looking up there and saw movement. It quickly quadrupled and then flowed across the ski line and over the cliff band. Spectacular. Flowed like a water fall for about a minute."
