Events of the day

Second skier on slope triggered a D1 soft slab that ran a couple hundred feet down slope. Looked like the new snow slid on old hardpack/wind board. The crown was about a foot deep at the top, tapering quickly down slope. The skier was initially caught in the slide, but then able to ski out.

Looking over at the tracks on Sunburst, it looked like at least a couple others had similar experiences today.
