Storm Skiing!

Avalanche Conditions

Flew into Mallard Lodge the day after the big storm on Mar. 10th and skied the last 3 days. We received 40-50cms of HST from the storm with dribs and drabs (5-10cms/day) each day afterwards. Winds were generally light from the SW all week.

Due to overcast/obscured conditions, we were only able to get into the ALP for one run. There was surprisingly little wind-affected snow up high and we spent most of the trip skiing N-E-facing TL features. Trailbreaking was difficult but ski quality was excellent!

We started off incredibly conservative, giving the large load of snow on 2 weak layers (FC/SH) lots of respect. One was buried early March (dn 50-60cms) and the other mid-February (dn 80-90cm). There was evidence of a widespread avalanche cycle on the flight into the lodge on Mar. 10th, mostly failing within the storm snow or on the Mar. 5 layer. Snow profile on E-facing TL feature produced positive ECT results as indicated below:

SSE dn 50
ECTP 12 dn 50 on FC/SH

We also had 2 Sc sz1 avalanches on Mar. 10th., but with little propagation. Slope tests often produced no results and I was surprised at the stability given the recent avalanche activity and positive ECT results. We stuck to supported slopes up to 30 degrees on Day 1, but with temperatures around -6C and very low density snow falling, stability and confidence in the snowpack improved rapidly. There was no natural avalanche activity, no signs of instability in any of our ski travel and by the end of the day today, we were skiing NE TL slopes up to 45 deg. Face shots all around. What a week to go skiing!
