We specifically wanted to check out the snow surface, the Leap day BSH/NSF, and the January facets.
In two separate testpits at similar elevations we found January rounding facets (1.5mm) were ↓150cm at 1F harness surrounded by Pencil hard rounded grains and rounding facets.
The Leap day BSH (generally 3-6mm in many locations) & near surface facets were ↓20cm and reactive in Compression tests, but didn't propagate in several ECT's.
Most of the surface was covered with fresh surface hoar and the conditions varied from powder on northerly aspects and shaded areas to gradually becoming more sun affected on solar aspects. Where sun was playing a role, translucent crusts had formed. The skiing was challenging especially on solar aspects, but hop turns enabled us to consistently link turns.
