Comments
While skiing over a steep breakover (approx 40 degrees at the break, but rapidly loosing steepness below), a small fracture propagated out to the left of the skier and released a small slide approximately 25 feet wide that ran about 100 vertical feet. It was about 10" deep, basically the new snow in the past 24 hours. The skier did not stop and we only saw the avalanche while ascending on the skin track after the run. We didn't examine the bed surface but it was likely some sort of density change in the multi-day storm, or possibly a very subtle sun crust as the slope faces southeast.
