We were skiing in the northern absarokas yesterday, and triggered a number of slow moving sluffs in the new snow that slid easily on the thick crust formed from the warmup last weekend. The sluffs were triggered in isolated steeper terrain (>38deg) but were able to pick up enough momentum to travel a ways downslope. We figured that a few more inches of load in the form of the new snow last night or windslabs forming on the ridgelines would make them more difficult to manage. We saw some shooting cracks at ridgelines due to wind slab development, but the attached image shows sluffs that traveled a fair bit down the slope, but didn’t propagate wider than the area affected by our skis.
