Crown visible during the day on ascent to Catherines Basin. It appeared to have released during the high PI rates early in the morning on the 29th. Connected slab that propagated through 2 distinct gully systems: All the way across Toilet Bowl (aka B) to the the rider's right side of the V Tree Chute area. Debris ran to transitional flats. Crown appeared to mimic stability test results as far as it's depth, estimated at 12 to 14 inches. Weak layer identified in the holes dug indicated it was running in moderate sized facets 1 to 2 inches below the "Snirt" Layer that was formed during the prefrontal phase of the latest event.
