WEATHER: similar to what Donny wrote in his ob, but there was a short period of significant S3 snowfall that accumulated enough to cover the old snow surface.

SNOWPACK/AVALANCHE OBS: Solid MF crust found on westerly aspects. Mostly all faceted snowpack found on northerly aspects with no slab evident, and on terrain steeper then 35*, facet sluffing to the ground was evident but slow, and not far running.

WEATHER: 1000: 36ºF, calm to light wind from north, visibly stronger winds aloft, partly cloudy.  PM:  Snow flurries, short periods of S1, no accumulation, graupel mixed in, cloud band must have been low-elevation because sun could still be felt; moderate wind from the north, no temp recorded, but clearly it cooled somewhat.

SNOWPACK/AVALANCHE OBS: Dug a pit at 10,250’ on a 37º east aspect.  HS 90cm.  No buried SH found.  2mm DH found at base.  Most remarkably the old 12/13 interface had the largest facets – some DH evident.  Had repeatable CTH22 (SC) on this interface.  Top 10cm going through diurnal faceting.  Two, old crowns (D2-R1) still present in “Rental Shop” along with a loose snow slide from the top.  This is not relevant to today’s conditions, but it was a great teaching tool.

Snowpack / Avalanche Obs: HS ranged from 50-120cms. Buried SH found roughly 20cms below surface and reactive to shovel tilt tests with moderate force and sudden planar fracture character. Not reactive in compression tests, as it would just become embedded in soft snow above upon compression force. Overall snowpack is mostly all facets F-4F hard. Moist and wet snow surfaces on open Northerly slopes. Dry snow holding on in dark timber on Northerlies

WEATHER: Clear, calm and warm – 35ºF @ 1000 and 47ºF @ 1500

SNOWPACK/AVALANCHE OBS: Traveled in meadow and lower slopes.  Three big whumpfs in meadows.  We could feel the drop and the crack was visible nearly all the way around us.  Ski pen would go from 5-10cm to bottomless trap door conditions.

AVALANCHES: Observed a few N-LW-R2-D2 avalanches emanating below cliff bands on south west slopes. Slides likely occurred within the past week. One slide traveled about 800 feet in a gully. The snow from that slide piled up high.

WEATHER: Mostly sunny skies and calm. Very warm.

AVALANCHES: none. small facet sluff behind 3rd skier.

WEATHER: warm, light NW breeze for evaporative cooling, occasional saltation of facets across snow surface. Measured 47ºF during lunch at 1400hrs at Green Lake.

SNOWPACK: AVALANCHE / SNOWPACK OBS: Interesting and terrifying snowpack structure on N-facing apron below north facing aprons. Dug mid apron and found 10mm SH, 45cm deep, below P-1F hard slabs, with P+ bed surface. Almost pulled plug right there, but continued skintrack traverse, spread out, had guests turn music off they were listening to, and continued 30m to windbuff and old debris, with no SH. Within wider coulior, snow remained turned-able, and pretty much F+ facets to ground. Wallow-fest. South facing slope, climbing back out was punchy and unconsolidated until you hit crusts 30cm deep and several more a but deeper. Wet, mature corn grains on surface. If not for various crusts, and old sled tracks, would have been more spooked.

WEATHER: Clear, Cool in am. Warm in pm. Overall mostly light to moderate winds from NW, vary warn while in the in the basins and light wind while on the ridgeline.

SNOWPACK: No new Wet loose slides where viewed from ridgeline, Bootpen on S slopes was 20-30cm. On NE slopes SH buried 20cm 20°

WEATHER: Clear, Cool in am. Warm in pm. Overall mostly light to moderate winds from NE

AVALANCHE / SNOWPACK OBS: A recent Wet loose from the ridgeline (probably Tue 10th) on SE @ 12,100 ~40* 2 small collapses along ridgeline (SE & SW @~10*) on thin faceted snow pack covered by wind hardened snow. Skied up to 40* on SE-SW without incident. Below 10,850 on S-SW aspects ~15:00 snow was unsupportive wet facets/DH with ski pen ~20-30cm, boot pen 1/2 way to China. Flats & SE were more supportive

AVALANCHES: No signs of instability

WEATHER: Broken skies. Calm winds. I counted 4 or 5 snowflakes falling from the sky.. But they were pretty big.

SNOWPACK: A profile on a NE aspect below treeline showed the Jan 11 surface hoar layer 25 cm deep, with fist hard, faceted snow above and below. No real slab over the surface hoar and no results on this layer, and we didn’t see any signs of instability on slopes up to 40 degrees.

Weather: Partly cloudy sky in the Washington gulch area with plenty of sun and warm temps to soften snow on sunny slopes. Farther west cloud cover looked overcast. Light winds for the most part.

Snowpack: Wet, gloppy snow surface below 10,000ft on sunny slopes and even some shaded slopes. Higher up the snow surface was cooler and crusts from the last few days where noticeable on slopes that had a more eastern tilt to them. Found buried surface hoar down 40cm below a 1f slab in the starting zone of coneys. Found the SH mid way down the bowl too, about 30cm down. Skied the bowl with many other tracks and still no obvious sings to instability.
