Avalanche Details

Recent avalanche observed on SW-facing slope of Tincan ridge below Hippie Bowl and at upper end of Southside ski run (see attached pic). Appears to have run on convex rollover with locally steeper angle than that for the general slope. Adjacent tracks would indicate that it was remotely triggered by skiers nearby. Did not investigate site, but looks as though storm snow of last weekend slid on old crust? Note arc-shaped fracture in snow surface 100 yds to lookers left of described avalanche. Looks as though snow fractured on similiar aspect and convex slope, but failed to slide. Sympathetically-triggered by the first avalanche?
