Found some giant avalanches!

Lizard Range and Flathead

The recent storm hit the Lizard Range with heavy precipitation and warm temperatures. This rapid increase in load was likely the trigger of these large avalanches that released on the early December persistent weak layer. What we noticed about these start zones was the rocky nature of the terrain, where the snowpack is a bit shallower. This reminded us that this persistent weak layer is still a player in the Lizard Range/Flathead region. We will continue to manage this problem by avoiding steep, rocky terrain features where the snowpack is shallow

Snow conditions were: Heavy. Weather conditions were: Sunny, Warm. We avoided: Alpine slopes, Steep slopes, Sunny slopes.

Avalache Conditions: Slab avalanches today or yesterday. Rapid temperature rise to near zero degrees or wet surface snow.


3 size 3-3.5 natural avalanches on the deep persistent crust facet combo from the early December rain event. These appear to have happened during the heavy loading last night or yesterday. Ran full path and up over the road into the Little Sand cabin.
