Quick Observation
We went back to McGee Creek to repair the disgruntled skin track
~1/2 - 1 inch new snow overnight at 3800'
As we traveled to higher elevations, we found widespread wind effect and a bit more new snow.
Cummulative storm totals varied at higher elevations (5400-6200) due to irregularities in wind distribution. On south facing terrain we observed 7-15 centimeters of new snow (11/19-11/20). And on north facing terrain we found 15-30 centimeters of new snow. Deepest accumulations observed close to ridgetop on windloaded/crossloaded features. In areas that were mostly protected from the wind, but also not densely forested, we found 12-18cm of new snow.
Winds were steady all day. At mid-slope locations, they were blowing 5-15mph and shifting directions quite a bit during gust. They were mostly blowing from SW, but periodically gusting (25mph) anywhere from NW to SE. On top of the ridge, winds seemed less indecisive about which way to blow. They came from the SW at 10-15mph with gust at 25-30mph.
South facing slopes harbored wind pressed powder in open areas and preserved uncosolidated powder in protected areas. We skied south facing slopes today.
We did not ski north facing slopes, however while skinning on the ridgetop, we wandered down slope a bit to make observations and noted that north facing was notably more "slabby". We stomped around a bit on suspect test slopes and found some cracking but nothing too alarming yet.
Another notable change in todays snowpack from yesterday, was that yesterday harbored a moist/wet slush layer (9-14cm thick-4F hardness) lingering beneath the new (11/17-11/18) melt-freeze crust and today that same layer was dry round grains and hardening to 1F.. (refer to McGree Creek snowpits from 11/19 to see said slush layer)
Skies were mostly cloudy/storming up high today with breif breaks in cloud cover. Snow was lightly falling S1 most of the day and we estimate about 1-2 inches fell between 8:00am and 4:00pm.
Pictures attached show active cornice growth on ridgetops as well as a treeless southfacing part of the ridge being stripped to the ground.
