4-5′ wind slab released just above Flattop trail at the gap between Blueberry hill and Flattop Mountain. This is a repeater path (slid last year in January and was also the site of a fatality in 2006).

Wind slab (hard slab) natural avalanche likely triggered late Saturday night or early Sunday morning (4/19) in a very wind affected area. Northeast winds funnel through this terrain feature loading 2 obvious wind pockets directly above the popular Flattop hiking trail. Often times both of these pockets will release simultaneously. This avalanche released the northern-most pocket only, leaving the southern pocket in-tact as of 1330 this afternoon.
