Wind Slab triggered on Bradley’s Meadow

I attached a few photos of a small wind slab avalanche (R1 D1)  from yesterday at approximately 7800 feet on the northern end of bradleys meadow. 

The slide was initiated by the second skier and although the rest of the slope was <30 degrees the starting zone was a NE facing steep cross loaded wind pillow just below the ridge. 

As my friend was skiing down he saw a crack propagate up and to his left and was able to stop on the side of the path as the snow ran past him. The  crown was approximately 30-40 feet and ran about 100 feet. 

Here are the coordinates of  a way point I dropped just above the top of the slide : 

45° 50.0218′ N, 110° 55.7420′ W

 we circled back and took a photo of the top as well...  let me know if you need anything else! thanks!
