Great but conservative weekend up in the Marriott Basin/ Wendy Thompson Hut. Upwards of 140cm of new storm snow from the last system, with a total snowpack depth of 270-330cm. Great skiing above 1800m Tons of wind loaded east and northeast aspects - looked tempting but I wouldn't have touched them with a 1000 foot pole. The entire ridge (west aspect) from Rohr lake north to the hut appears to have slid naturally on Friday night/ Saturday morning. Sliding full path in many cases (including climax path), and stepping down to ground in many spots. Oh, and the ski out below 1700m was hands down the worst skiing I have experienced in my 30 years doing the sport...
