Comments
Slide happened sometime Saturday.
Very large wet slab avalanche, looks to have gone full path and crashed into Peyto Lake. Estimated 20-30m wide and 2-3m deep where summer trail crosses the slide path above the lake. Ground vegetation exposed another 5-10m both sides of the debris. Possible start zone photos taken from Bow Summit upper lot.
