I was up in the Uintas today in the Weber Basin drainage where I triggered this slide at 10500 on a NW aspect. There was 25 cm's of new medium density snow. When I was skiing just below a roll over midf-slope I felt it was time to depart. Just after skiing off the main line to the skiers right to a less dangerous location I looked over my shoulder and noticed the crown and snow running. Upon investigation I was surprised to notice the snow did not slide on the new snow/old snow interface. Instead, a 5 cm layer just below the new snow capped on top with a light melt-freeze (which the new snow is sitting on top) was sitting on top of another melt-freeze crust layer (~1 cm thick) with near surface facets on top. This is the layer that failed. Looking at the first pic you see my first tracks lookers left. Notice just before I kicked out, I skied over a rock. Since this slide ran on a persistent weak layer, although I am doubtful, I was wondering if this is where I triggered the slide.
