Comments
Riding the NE ridge of Patsey Marly. Observed wind loading and noticed some fat wind drifts dictating wind transport from the W/SW. Trenched a hearty turn approx. 4' from the edge of the ridge and the wind slab shattered from my heelside edge. No one else was in the area at the time. I'm not totally sure how far it ran. The majority of the slab seemed to slide almost the length of a football field and it is likely that some of the snow ran to the base of Patsey/Wolverine Cirque. I estimate the slope was around 36 degrees and did not want to venture out onto the slope to take better pictures or have a better look because there is still a persistent slab danger.
