First Day of an AST-1 course. Good news/bad news: the riding was half decent but, unfortunately, there's up to 20mm surface hoar buried down 27cm, which lays on top of a crust. Uncertain about presence of the weak layer at higher elevations.

Couple small avalanches observed at Catch Basin and just below Hummer A chute (possibly hummer B as well, but hard to tell in the flat light from afar).
