A significant natural/ skier triggered cycle today in mid and upper LCC S facing terrain- Superior triggered around 0730. Others from around 1400 with good evidence of surface refreeze/ cornice fall being a major contributors. Most events initiating as shallow but widely propagating damp/ refrozen storm slabs in upper elevation terrain with some entraining/ stepping down as large wet slabs in mid elevation constricted terrain- these running long distances and producing large (15- 20ft depth) debris fans. Most significant events in S facing Little Pine East and Maybird paths.
