Comments
Wind was blowing at the time from the south over the small ridge piling up denser snow in the lee of slope on the south side of a small gully. It must have been depositing the snow for awhile because you could see where the wind deposited snow contact was with the old snow to the south. One snowshoer walked almost on top of this contact and fractures propagated immediately after which the snow slab slid into the gully breaking up as it slid. We had just been talking about how the wind was building up the snow on the edge of the gully. We did not feel in danger, but we thought it was interesting and worth sharing as a small example of the conditions today and the hazards that are still out there. Thanks for all you do.
