Touchy windslabs on Plewman-Elgood col on East aspect at 2150m. Triggered 5 or so from kicking cornices down etc, as well as one canine remote from 3m. Slab resistance 4F, debris run length 100m max with none running the full slope. Windslab sensitivity dissipated up Plewman ridge onto NE slopes as well as up Elgood ridge onto SE slopes. Propagation up to 50+ meters wide, slab thickness typically 20cm but variable. Moderate to strong winds were present immediately prior to triggered windslabs.
