Small wet loose slides from our ski tracks around 1pm. These ran a surprising length even though they were small.
Did you observe any avalanches?
Size 5: Could gouge the landscape. Largest snow avalanche known
8100 - 9000
An incredibly large serac fall from Colfax peak sent an impressive amount of debris down the glacier. Car sized blocks travelled over 0.25 miles. Unsure of release date but it seemed recent
Signs of Unstable Snow
We traveled up the Coleman-Deming route today up to 8300 feet. Our goals were to stay away from overhead hazard and watch out for glide cracks and opening crevasses with the heat.
Snow is rapidly melting beneath the Kulshan cabin site, and travel was easier on foot below then. Continued on skis from the cabin site on continuous snow. Snow was soft but a breeze helped keep it consolidated in the early morning hours.
Upon reaching the lower reaches of the glacier, we observed evidence of multiple avalanches that seemed related to the heat. Wet slab avalanches on steep S facing terrain across the Roosevelt glacier, serac fall debris and wet loose slides (D2-3) from Bakers west face, and a massive serac fall from the N face of Colfax peak. This serac fall made us feel that turning around was the best option for the day at 8300ft.
We enjoyed nice corn from 8300 to 6000ft around 11:30am. From 6000-4000ft the snow was heavy mush and began to entrain in roller balls and wet loose slides (D1) easily.
When the breeze wasn’t present it was HOT.
Observed Avalanche Problem #1:
Wet loose avalanches on the upper reaches of Bastille Ridge. They appeared to be point release triggered from rocks/cornices above and were located in steep rocky SW facing terrain around 7200 ft. The crowns appeared to be multiple feet deep and spanned 200+ feet
Observed Avalanche Problem #2:
Glide cracks on rocky terrain on the snowfield beneath the Coleman glacier near Gargoyle Rocks. D2. Many similar glide cracks were opening on rocky terrain on many aspects.
