Snow surface was dry at the pit but sun exposed slopes saw some surface melt. Air temp warm ~30 deg. cloud cover 0%
east slope at 30 deg steep 4000 feed above sea level.
Snow depth 120 cm
There were no strong boundaries in the snow . . .
Shoestring Gully is in great, snowy condition for December. It showed signs of recent avalanche activity and windslab formation. A mitt pit at around 2,200′ in the first snowfield of the gully (WSW aspect) showed layers of one-finger-hardness . . .
unbreakable crust with skis, boots broke the crust down the left gully. See photos for snow pit info location and photo of the pit.
In an isolated ENE terrain feature at 4800’ I dug a pit down to a firm layer. HS 185cm. I performed a CT which resulted in a CT12 at 115cm, Q2, on DF. There are several layers of facets between the observed crust layers. This failed BELOW a crust . . .
Lip/ center bowl slid on Friday evening from the new 1.5” snow transported on high winds and reloaded. Debris in runout soft. Sluice has not run and has fresh suspect windslab.
Right gully is variable snow with both bulletproof and soft . . .
We climbed Gully #3 from Hermit Lake to the ridge. The lower third was post-holing in breakable crust with very sugary snow beneath while the upper climb was supportable melt-freeze crust (from December 3). Cross-loading over the past week has left . . .
Found limited amounts of 2.4″ new snow loaded into Huntington Ravine. New snow was only found in isolated areas. Surface conditions to the right of the Fan and beneath Damnation, Yale and North varied from finger to pencil hardness wind board, . . .
.06 SWE fell early in the morning, likely around 2 inches very low density snow. Northwest wind for a couple of hours in the 60-70 mph range moving snow in plumes this afternoon. Small human-triggered avalanche in Right Gully ( plus another but with . . .
Large areas of hard wind slab yielding hard but clean failures in stability tests, with smaller and fewer areas of soft wind slab which remains reactive, producing easy and clean failures.
Able to intentionally skier trigger the small pocket of soft . . .
We climbed and ski Diagonal, The fan at the bottom on top of the bulge was of greatest concern, hand shear pulled easily we where able to mange and avoid the area on the way up and down. The snow in the gully varied in depth from 50cm to 150cm +. It . . .
