Primary Problem: Wind-Drifted Snow
Bottom Line: New snow and wind-loading are the main avalanche concerns today. They are creating instability in the upper 1+ foot of the snowpack, and the weaker, faceted snow near the ground is more difficult to trigger, but not impossible. Rocks sticking out in starting zones indicate shallow areas where a person could trigger a large and deadly slide. Today is a day of active loading and the snowpack will be most sensitive to triggering, both naturally and by people. Dangerous avalanche conditions are back. Be careful getting near avalanche terrain and be especially mindful of terrain traps.

Collapse in beehive
Beehive Basin
Coordinates: 45.3187, -111.3840
Caught: 0 ; Buried: 0

From Obs: "Had a pretty interesting collapse this afternoon while touring up the east ridge of Beehive. The slope I was on I measured at 30° at the highest, was below treeline but in a small meadow. The surface had melted and refroze. As I was touring across the small slope stomping to the to break the surface to set a better skin track the whole piece broke (150' wide by 50' down) together and moved down slope about 6". I quickly dug a little bit where it broke from the rest of the slope and it seamed to break near the ground, ~ 50cm and with the naked eye I could see large depth hoar crystals and little to no rounding.

While I do think it was simply a collapse I was very surprised this happened and the way this whole piece moved on such a low angle slope. I hadn't seen something like this before. Guess it lines up with just how weird this season has been.

  • An avalanche we either triggered from 750-800 feet away or it broke naturally.

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."
