There is a 1-5cm breakable temperature crust on all aspects below 1700m. Also a sun crust on solar aspects to at least 2100m. Freezing levels on Saturday were around 2200m. The midpack is mostly solid but there could be a Feb 13 interface down 20-50cm as a suncrust on solar aspects and a facet layer on polar aspects.
