Hero's Knob Natural Size 3

Heard a big avalanche come down skinning towards the Hero's Knob back bowl area. When we exited the trees saw that a size 3-avalanche had slid. The crown looked around 2m tall and maybe 50m wide. There was some debris above so our guess was something fell on it and triggered a weak layer. Debris field was very large, ~100m wide and ran for ~500m. Looked like there were some other crowns in the same bowl, probably 1-2 days old from the same storm slab
