Touchy storm slabs on Seymour yesterday Saw a few size 1s, including the two below, both skier-triggered (probably patrol). The first is on a south-facing aspect on the north side of Suicide gully, about a 15cm crown, visible from the main snowshoe trail. The second is a NW-facing slope below Mystery Peak, it slid onto the Manning cat track. Probably 20-25cm crown.
