Quick and dirty report from the Duffey. Rohr Ridge skis amazing! Perfect low density pow and generally well consolidated. Rain crust exists on the first 200m above the highway then dissipates. Skied S/SW ish aspects in steep-ish trees with no activity noticed apart from some moderate sluffing . Solid cornice growth on the North side of the ridge and quite a lot of wind affect around ridgeline. ECT yielding no results worth boring you with. We didn't notice much natural activity from the past 24 hours on the terrain we stuck to. Stayed clear of steep North-ish slopes especially those subject to wind loading and probably will again tomorrow!
