Sz 2.5 Skier triggered slab avalanche on the E aspect of Ymir peak, initiated from the approach to "the bench". We did not see it occur, but suspect this April 20 am based on talking with other skiers in the area. Wind deposited new snow failed on small facets on old sun crust. Crowns average 40-50cm, 10-30cm at trigger point. 60+ m wide in upper start zone, 100+ m wide below the rollover. Sa sz 1.5 on NW aspect of Ymir, above Kubas chute entrance. Occured April 19, apparently no involvement. (Second photo)
