Drove Buttermilk Rd to snow line at 7200 ft.
9:00- 7200 feet. Remaining surface beginning to melt but still supportable for walking. Clear skies. No wind.
10:00- 8800 ft. Skinned up east facing lower apron of Basin Mountain. Snow surface melting, ski pen less than 1 cm. Old (2-3 weeks) avalanche debris on these slopes.
11:00- 10,200 ft, Continued up east facing slopes. Surface melting. Ski pen 1 to 2 cm. At least top 20cm of snow surface moist. Light wind. Clear skies but increasing high clouds.
11:30- Wind gusts becoming strong. Small amounts of downslope snow transport. Ski pen less than 1 cm.
12:00- Began kicking steps at 11,200ft up southeast facing gully (see map). Boot pen ranging from 5-20cm. Quite alot of old avalanche debris in lower part of gully. Snow much less supportable near rock outcrops. Occasional creep cracks seen. Snow surface moist. Some high clouds blocking solar input.
1:30- Reached ridge top at 12,800 ft. Moderate wind. Mostly sun. Tair= -2c. North aspects of ridge still had soft, wintery snow.
Skiing extremely variable on way down. Soft snow on south slopes at 12,600 ft. Quickly turning to refrozen corn, firm avalanche debris and challenging skiing. East facing slopes from 10,200 ft to 8,400 ft soft, spring type skiing.
