Comments
Touchy conditions early morning during period of heavy precipitation intensity - easily snowed at rates of S5 to S10 (2-4" per hour) at times. Ski cut steep slope about 200' skiers left of Two Dogs while approaching Upper Days and pulled out 20 cm (8") storm slab that ran on the frozen crust/dust layer underneath storm snow.
