Decent sized slab avalanche on E face of mt Blackmore. Crown visible in photo #2, possibly skier triggered but unable to confirm.
My partner dropped first from the top of Blackmore down the East face and did a ski cut at the top and remotely triggered a wind slab. When he did his ski cut he was about 50 feet above the crown.
From email 3/12/22: "Hi there, just wanted to send you guys a neat pic of the climb, Code Red in Flanders from today 3/12. There was ice debris several hundred meters downslope from the pillar, which broke off at some point..." Photo: C. Robinson
From obs 3/12/22: "Upon descending a ~35 degree slope, I (the snowboarder) kicked loose a wind slab that propagated 100 feet wide, 8 inch deep (max, 4 inches at edges) wind slab that traveled approximately 300 feet (entire slope over 30 degrees) before settling in 2 debris fields, each about 30’ wide and with a maximum of 2’ depth. No one was swept by the debris/buried/injured."

From obs (3/10/22): "Today we triggered a small pocket of wind loaded snow while ascending (bootpacking) the East ridge of Blackmore. The convexity broke about 1 foot down and propagated about 10 feet wide. It ran the entire distance of the East face ~800’. "
A second report noted additional skier triggered wind slabs on Mt. Blackmore.
