I'm guessing this slide took place over the weekend, likely on Sunday. The slab boundaries are not very big, but the slide did cover a few hundred feet vertical. It looks like it was a remote trigger since the nearest tracks are several feet away. It took a bit of looking before I felt mostly confident that surface hoar was the weak layer. It has similar characteristics of other recent slides in the area where surface hoar was involved.

It looks like the slide first failed at the surface hoar layer then stepped down to weak depth hoar at the ground.
