Persistent slab explosive triggered at Big Sky

From BSSP on 12/15: "For the 4th day in a row we triggered a persistent slab avalanche on the early November crust/facet (2mm) combo.  This time the right side of Lenin main failed w/ a 4lb shot and ran full track well past the top of Shedhorn... The slide was approx. 150’, 5’ at its deepest at the crown and resulted in a solid size 3 avalanche."
