Notes

From IG: "Avalanche in the crazies that caught and carried me today. There were quite a few cars at the trailhead so I thought I’d share so maybe more people knew what the crazies snowpack is like.


Hard wind slab on a NE aspect at 8000ft. The whole seam was about 300feet wide and the toe was maybe 100 feet below the crown at the furthest. Collapsed on buried surface hoar on top of a freeze crust."
