Evaluate temperatures closely when choosing your skiing and climbing objectives for the day.
Higher elevation ice on north aspects is still in good shape.

This overlies Jan 18 crust extending all aspects up to 2000m, and higher on solar aspects. Well settled midpack, with facets above Dec 4 crust, buried 150-200 cm, above Nov layers.
