This human triggered avalanche likely occurred over the weekend (see photo page) and failed on the surface hoar layer. It released just above mid slope and was possibly triggered near some trees where the slab was thinner and the rider was able to break through the rain crust and into the surface hoar layer. Much of the slide has been blown back in and today's storm and poor visibility did not allow for a good observation.
I was getting repeatable CT19 Q1 results on surface hoar along the flank of the slide.
The extended column test was ECTP 24 Q1on surface hoar.
