A unicorn day in the Castle for an AST

We were in the Castle Ski tour terrain on Haig for the day with an AST course. We found 5 cm of new snow over a breakable melt-freeze crust from the warm temperatures and precipitation on Friday. Total snow depth 155 cm. The day was warm and there was almost no wind for the whole day. The snowpack is well consolidated, especially in open areas where it is wind pressed. In the sheltered treeline and below treeline we found a softer layer sandwiched between the Dec 26 crust and the most recent crust. There was decent visibility and we saw no recent avalanches.
