A proper mixed-bag spring day in North Terrace, started off in the sun and found a 2cm breakable crust to 950m where the crust finally gave way to wind pressed styrofoam. Temps were warm up to 900m which thankfully melted the crust for our egress. Some clouds moved in with ridge top winds and kept the alpine snow cool. We saw widespread storm slab crowns (size 1.5-2) on the NNW aspect, all starting near ridge top @1400m and running about 1/2 path, no sign of stepping down to older layers. No concerning instability found on our objective (West face) but moderate planar results in a hasty pit down 20 and 25 cm- above and below a 5cm 4 finger density slab
Snow conditions were: Crusty, Wind affected. Weather conditions were: Sunny, Warm, Windy. We rode: Alpine slopes, Open trees, Sunny slopes. We avoided: Steep slopes. Riding quality was good.
Avalache Conditions: Slab avalanches today or yesterday. 30cm + of new snow, or significant drifitng, or rain in the last 48 hours.
