Avalanche: Uintas

I happened to be in the area of Double Hill this afternoon and observed this snowmobile triggered slide when riders were ascending a northeast facing slope on the south end of Double Hill. As one rider crested the hill he triggered a mostly shallow soft slab avalanche that he was able to ride out of. One rider below also rode through the slab as it broke and one rider turned out and avoided it. I think we were all a bit surprised to see a slide break that was this wide and connected. Prior to this avalanche I was watching riders break out some very small soft wind slabs just off the ridge line that were mostly harmless. I think the combination of a slightly steeper slope angle and just the right slope orientation where the recent wind and new snow created this slab. I don't think this is a widespread problem as riders on the north end of Double Hill were not triggering any slabs, just some minor new snow sluffing.
