Instructed at an AIARE 1 course. Took following temps at Hermit Lake at roughly 11:45am-> TAir: 0c, TSurf: -6c, T10: -8c, T20: -9.5c.
We did some digging near Leve Rock in Tuckerman Ravine. Huge variability – I found HS 190cm with HS 85cm roughly . . .
Observed fresh avalanche crown with ski tracks entering in from lookers right. Slope SE, slightly convex, approx 40 degree slope angle. D1 hard slab, 30′ wide with a crown height 20″. Very little debris remained possibly due to fragmenting & . . .
Clear skies, calm wind. New snow Tuesday and Wednesday followed strong W wind has increased the size of snowfields in Tuckerman & Huntington Ravines, particularly mid-slope well below the sky line. In Tuckerman Ravine the sluff piles continue to . . .
On and off again clouds provided on and off again visibility. Calm W winds had little effect on the moderate amount of snow falling. A thin rain crust is present near and above tree line. Depth of the rain crust within the snowpack varies depending . . .
We observed anywhere from about 10cm to 30cm of new snow on top of the Dec 15 crust in the area below The Chute and Left Gulley. (The crust varied from about 5cm to 20cm thick depending on aspect and was knife hard.) Multiple hand shears and tests . . .
Snow (above Dec. 14/15 crust) leading up the fan to Odell’s, and within the gully itself, was unconsolidated, ranging in depth from 0″ to ~8″, mostly in the lower end of that range. Crust was ~2″ deep in places, but consistently soft/porous enough to . . .
Clear blue skies & moderate/strong WNW wind. -2F (at 6262ft.) Majority of the snow pack consists of heavily textured, thoroughly refrozen snow after the rain on Saturday. Little continued snow transport observed at the ridge lines above the bowl. . . .
Instructed at an AIARE course. Roughly 55cm HS next to outlet of Hillman’s Highway near cache. Rain crust on top with some 4F and F hardness midpack with another rain crust below. Did CT and ECT tests with some hard planar results but no real . . .
Warm up and rain the last couple days condensed the snowpack considerably. Top firm alpine snow crust is about two to three inches thick. Beneath is dense snow of variable depth depending where you are. Lots of water still running underneath the . . .
Warm day with light precipitation before freezing temperatures overnight. Two skiers headed up Left Gully.
