Red Flags Comments
Continual cracking and collapsing as we skinned. This was caused ranging from the first person to the seventh person on the skin track (our group of 3 used the same skin track for 3 ascents). Many of the cracks were very large propogating for 15M or more.

Problem #1 Comments

See included video. The PST test appears to be across the slope, but the slope angle was very low (20 degrees) and the angle of the camera causes this to look like it is across the slope.
