This slide in Super Bowl fits the category of "pockets of considerable" for steep, thin rocky areas. It was likely

A small slide on the south end of Double Hill also looks to be human triggered. This one we think may have been triggered while a rider was decending from the ridge. We guesstimated the slide to be 3' deep at its deepest point, 150' wide 250' vertical and involved weak faceted snow at the ground and is on a northeast aspect above 10,000'. Lots of steep slopes were tested this past weekend.
