More detailed information about the avalanche: 

Report of a skier triggered avalanche today in the Rock Creek Drainage just above Hilton Lakes.  Skier triggered slide during a turn at red circle in attached photo, releasing fresh wind slab about ~75ft above him (~200ft below ridgetop).  He was carried 100-200' down slope and thankfully came to rest uninjured, as the slide continued downslope ~1600' horizontal distance, and ~1000' vertical with toe being just above the lake.  The party reported that the slope above the crown near the ridge appeared stripped from the wind, and that the meat of the windloading was lower downslope than expected.

Winds were blowing and actively loading the slope today.
