Quick report
Two skiers ascended and descended Green Creek Couloir. Booting conditions were firm and secure in the morning. During the descent, dry loose sluffs were triggered on steeper pitches, requiring sluff management and controlled skiing. Ski conditions improved lower in the couloir and on solar aspects, where corn snow developed by midday. We managed sluff by skiing one at a time and moving out of the fall line where possible. Clear skies with strong solar radiation throughout the day. Overnight freeze produced a supportable crust in the morning. Air temperatures started in the low 30s °F and warmed into the mid-40s °F by early afternoon at 10,500 ft. Winds were light and variable, with no active snow transport observed. Snowpack remains shallow and variable. In shaded terrain, we found 20–60 cm of settled snow over older crusts and faceted layers. Solar aspects had a melt-freeze crust that softened with daytime warming. In the couloir, the upper snow surface on shaded and steep northerly aspects remained dry. On solar aspects, the surface transitioned to corn by late morning. Hand pits showed the upper 20–30 cm of snow was generally well bonded, though loose surface snow was present in steep terrain. Faceted snow near the ground was present in thinner areas but did not show signs of reactivity.
