We skied up to convexity which looked to hold a thin wind slab. Talked about it beforehand and determined it might rip, but would be shallow and easily escapable. I dropped in first and, sure enough, the slab ripped and propagated across the entirety of the small terrain feature. I saw it fracture all around me and knew it was shallow (as predicted). Easily rode out of the avy path without consequence. Avalanche only traveled around 100' and was slow moving. All said, still relatively surprising considering slope angle and elevation.
