Ursus Minor sz 2.5

Tour to video peak. Observed rain crust down 10-15cms up to 2200m where it started to disappear. Sun crust observed on S SW aspect starting around 2290m. Dug a pit below video at 2370m, East aspect, 24 degree slope, thermometer read 0 degrees in shade (significantly different to forecast temp). 3 column tests produced variable results. 1st was sudden planar down 60cm on what looked like decomposing surface hoar. 2nd was CTH 30 resistant planar down 40 on unidentified layer. 3rd was CTM 16 down 80 on facet layer. 2 other groups dug pits in similar locations with very mixed results. At the top of video around 12:30 we observed a sz 2.5 skier triggered avalanche off the South West face of Ursus Minor below the summit. It ran over the cliff face and into the gulley feature below. Start zone looked very shallow with rocks poking out and was significantly sun affected.
