<p>Witnessed 3 skier triggered avalanches on 04/14 Upper portion of Mt Whymper North Bowl: a point release/sluff slide on the west side of the upper slope; a point release/sluff slide on the east side of the upper slope. A slab avalanche occured minutes after the sluff slide in the east portion of the upper bowl: likely skier triggered as there was someone on the slope. Hard to tell if it was new instabilities introduced from the previous slide.
During our descent we came across another slab release in a small chute. It's assumed it was skier triggered though I didn't confirm when we met the people in the parking lot who may have caused it.
All the avalanches above were size 1.5 to 2</p>
