More information on a size 1.5 near Parkers ridge behind Hilda hostel can be found here (Here).
30cm of new snow redistributed by strong winds has formed windslabs and storm slabs. This overlies a weak surface hoar and facet layer or a melt-freeze crust on south and west aspects. The snowpack is 35-45cm in depth with a weak base.
