Saw 7 natural avalanches today in the June Backcountry area today. All seemed to have released naturally during or right after the storm.

Five were on Mt. Wood Two of those were small, loose dry looking slides running in NE chutes. Three looked like R3 D2 slides that ran on E and NE aspects. Was unable to see a crown line. They could have been slabs that released during the storm and the crown fracture line blew back in with the consistent winds on ridge tops even this morning. All three of those slides ran down through the lower angle apron of Mount Wood. Slide 1 came out of the popular ascent gully, slide 2 came out of the E- facing chute off the summit and slide 3 came out of the next gully north of slide 2. 

Saw a prominent crown fracture line in the Negatives, about 50 m long. NE aspect underneath prominent rocky shoulder just to lookers left of top of Negatives. Ran probably 100m long. R1 D2. Dry slab, natural. 

Another prominent crown fracture was vivible on the NE aspect below the big rock face near the Two Teats.
