Triggered a size 1 avalanche on the ascent at treeline and two small size 1s via ski cutting on steep, slightly convex features. All crowns averaged 30-40cms and ran on buried surface hoar sitting on top of a very thin crust (about 2mm thick). Observed a few other size 1 avalanches triggered by heliskiers with the same characteristics. Propagation potential was low, as new storm snow was still unconsolidated, but we were surprised by how far the snow ran.
