ECTN 25cm down on new/old snow interface. PST 100 Arr on same interface. Skied the main avy path down to Sweathouse creek, finding wind affected but enjoyable snow in top 700' and fantastic hippy pow down to creek. Also skied the S facing main gully of Sweathouse creek slightly west of main Gash path. Sun was beaming but no signs of instability observed, snow skied well for hot pow.
