Settlement and cracking at Corbin Pass

Following in the skin track set by a party of 2 ahead of us was close to a tree when there was a loud settlement and an at least a 15 m long crack shot across the slope running tree to tree. Open treed South slope at 2000m. Skied conservative line in trees and small features avoiding large planar slopes.

Extended column test complete propagation across the block on the 30th tap. Failed on surface hoar on crust.
