Skied Ullr's couloir today. Wind was consistently strong from the SW. Wind transport was limited to facets and shale. Large cornices loom and block all the chutes and couliors along the ridge except ullrs. Cornices are very hard and didn't want to move. Temp was below freezing, no solar effect wet loose activity started on solar aspects by the time we skied. Thin (5-10cm) windslab isolated to immediately below ridgecrest and on cross loaded features lower in the couloir. Some sluffing of 10 cm of soft surface snow through the rest of the line. No other snow stability concerns.
Snow conditions were: Powder, Wind affected. Weather conditions were: Windy. We rode: Alpine slopes, Steep slopes. Riding quality was ok.
