Ski Pen: 40cm
Foot Pen: 60cm
Wind: Light from SW and increasing
Gorgeous bluebird day. Winds were calm in the AM increasing to Mod SW by late PM
Small to large wind slabs N-E-SE @ TL & ATL
Dry loose on steep slopes all asp & elev
Traveled primarily on S and N facing terrain btw 9000-10200′ BTL. HS 250-300cm on N terrain. HN48 35cm & HN72 55cm, light density. Powdercats also reporting similar amounts (HST 22″) on Soda over the past 72hrs. Lots of natural activity on S-SE facing slopes as soon as the sun came out resulting in multiple Loose Dry’s to Sz 1.5 running 800ft to valley floor. No results in stability tests on N asp @ 9700, 35*: ECTX, CTN.
A++ on cold aspects with face shots galore. Southerlies got cooked and developed a 1cm+ sun crust by day’s end.

Gorgeous calm crisp bluebird day with 1″ of new snow and evidence of some light wind transport overnight.
Large persistent slabs unlikely on E-S-SW all elevations
Large wind drifts in the entrance to Rock Chopper and in the gut of Bruiser. Some sluffing on steep shaded aspects. No other signs of instability, no cracking, no collapsing, no recent activity. Did not dig pits today.
A+ all asp above 9000ft
Ski Pen: 15cm
Foot Pen: 30-60cm
Skies were overcast with on and off flurries most of the day and a trace of accumulation. Winds were calm. Temps were crisp and topping out at 14F.
#1 Large storm slabs possible at all asp & elev
#2 Large persistent slabs unlikely on on E-S across all elev
HS generally in the 220-260cm range above 9,000′. Ski pen 15cm. Boot pen 30-60cm depending on aspect. Dug a couple pits and found good snow structure in the upper meter+ of the pack, with the notable exception of a melt freeze/facets combo at the new/old interface down 80cm that was reactive to stability tests. No cracking or collapsing observed. Some sluffing.
Pit #1: SW, 9700′, 20* slope (Girly Turns): HS 215cm, ECTP22 SC below Feb 6 melt/freeze @ 80cm
Pit #2: ENE, 9300′ (New Years Bowl): HS 230cm, ECTN @ 60cm in storm snow, CT20 RP @ 70cm in storm snow, CT21 & CT22 SP @ 80cm on facet layer below melt freeze crust.
Skiing was excellent across all aspects on a supportable base with boot top champagne. Low angle was skiing great due to fast surface snow. Sluffing on steep slopes.
Ski Pen: 20-30cm
Wind: Mod NW
#1 Small-large storm slab likely on all asp and elevation
#2 Large persistent slab possible on NW-N-SE at TL & ATL
HS200cm SW @9900′, 1″ breakable sun crust below storm snow
HS200cm NW @ 9400′, F to 1F progressive hardness in top 1m, ETCN @ 30cm.
Top 8″ of new snow is upside down and easy to trigger. Lots of activity, incl. naturals and skier and remote triggered soft slabs. Slabs up to 10″ deep running on 1″ thick sun crust (solar asp) or within the lighter density storm snow. Sluffs were running far and fast in Bruiser and North Woods zones.
Good skiing on cold aspects. Could feel the sun crust on solar aspects.
The theme of the week was warmth with consistent light to moderate winds out of the SW. Twice in the past week we had highs of -2c with lows @ -3c. -9c was the coldest temp we saw. 31cm HST mostly in the last two days (Thur/Fri) reset the surface conditions. Mod to Strong alpine winds throughout the week, mostly from the S and SW, but occasionally from the NW & NE created wind effected surfaces below the most recent snow. There have also been a few thin rime crusts develop in the past week.
Warm temps & sustained winds settled out most of the upper & mid packs. Over 2 weeks we saw 26cm of settlement in HS & boot pens from 60 to 25cm. Also, in last 2 weeks snowpack tests trended from Sudden to primarily Resistent and even Progressive Compression. For the last 4-5 days we’ve primarily been concerned with surface & HN instabilities, mostly wind slabs. We still have the Nov CR/FC laminates on our radar in steep, unsupported terrain, but have seen no activity in 2 weeks in the range. We’ve also seen significant cornice growth in the last 2 weeks with a few small failures.
We’ve seen no mid pack avalanche activity, and nothing of note early in the week. Friday saw our heaviest snowfall of the week and we experienced many Dry Loose and few small Storm Slabs. All sz 1 and mostly predictable in steep features. Saturday was our most active activity. 2 Na Wind Slabs. 1 in Viking Holler Main sz 1.5-2 and 1 in Grizzly Chute (smaller left side) sz 1.5 most likely at night. We also ski cut 2 sz 1’s in the Grind and Lower Grizzly Chute on a steep cross-loaded feature. Wind Slabs are the primary concern in the short term.
