Sunday, January 21, 2018 - 2:45pm
Rider(Snowboarder based on tracks) triggered Wind Slab on east face of Black Mountain (R1, D1), elevation ~10800', East aspect , ~100' x ~150". Looked to be shallow, slope prone to wind loading with West to Northwest winds. Very small sloughs on test slopes where distrubed.Picture quality is poor due to flat light. Highlighted rough outline of the debris. Track exited out of the debris and continued down the route.
