Steep convex test slope with leeward loading above gully feature, well below treeline but with active wind loading observed through aspen/birch groves. Touchy and propagated all the way across feature and past a subtle aspect change (extended to red arrow in photo, ~100' wide) Observed instability limited to specific areas with lee & cross loading on steep, unsupported terrain. Areas with the wind deposition did seem to have quite a bit of energy and pop to them.
