Toured from Blackcomb through guide notch to Spearhead glacier. Rode the glacier (open crevasses but good visibility) and did a sunny lap from Corona notch back to glacier flats. More wind effect on the E lobe of the upper glacier. Return via Corona bowl was shark-infested, beware. Observed a number of skiers pushing into steep, shady, consequential terrain without incident, but we were wary of wind slabs and potentially lurking deeper layers. Storm/wind slabs seemed to be mostly healed. Lots of powder available for transport.
Besides avalanches mentioned in pictures, observed wide crown lines at the top of the glacier below Spearhead peak. These did not seem particularly deep and probably released naturally towards the end of the storm.

Beautiful Day for Some Singing
Skiing was great! Lowish angle really avoiding any convexities especially lee loaded looking features. Some crustyness but it was a blast for a lap. Lots of people out. Sunny, kind of chilly so limited thermal stuff. Yay fun, friends, and sharing info!

Whirlwind
Tried to ski top of whirlwind today. Size 2 naturally triggered avalanche on Fissile in front of the up track to top of Whirlwind, decided not to hike and ski it. Great track down into the valley, with excellent snow from the recent storm.

Oboe quick check
Photo looking back to cowboy ridge. Hiking up from oboe creek to oboe found snow depths between 30cm-60cm. Crust under the storm snow was very supportive. Couldn’t get the handle of my pole through it in multiple spots. Did a quick hand shear test and snow was bonding well to the layer and was not well consolidated, did not feel slabby.
Did not see any signs of instability, did a few hard cuts on mini convexities and nothing moved.

Good Times Cowboy Ridge
No Signs of avalanche activity around oboe or cowboy. We avoided the obvious convexity at the top of cowboy ridge, as did everyone else. However, a ski cut nearby wasn't able to make anything move. Ski penetration approximately 25 cm into very dry powder. Despite the very strange surface of the snow, after it's playdate with the wind, the surface doesn't feel wind affected. Does not feel/behave cohesive like a slab. Just makes everything a little more aesthetic.
Oboe saw a lot of traffic, cowboy was surprisingly less so. Picture attached was taken at 3:00 p.m. Few parties still out there.
Great day.

Decker Lake
Team: J Budd IFMGA, Mel W (CSGA2)
Trip: Body Bag to Circle Lake and then Decker Lake. Decker Lake to Decker Meadows and then out D Ridge.
Winds were moderate and gusting strong. HST ranged from 5cm - 40cm on lee aspect from B Bowl down to Circle Lake. Snow transport was light to moderate. Up tracking from Decker Lake, working benches to avoid overhead hazard from Decker. Mel put a kick turn in and a shooting crack propagated 15-20m across to convex slope and initiated the avalanche which propagated approximately 100m to prominent ridge toward circle lake. Crown at convex roll 40 cm and 10cm at rocky ridge. Bed surface Dec 30 Cr. 4 Finger resistance at crown.
Second avalanched observed on way out:
1400 hrs, Fingers Chute/Decker, Sz 1.5, NA

Spearhead Gl
Difficult vis conditions on the spearhead glacier. From Guide Notch down to the flats was hard navigating through the crevasses in near whiteout. 6-8 cm new snow and snowing about 1cm/hr. Mod - strong wind from the east. Old tracks still visible in husume with minor wind loading at the entrance. Hs170 on spearhead glacier flats.

Bodybag to Spearhead Glacier
Skinned up bodybag, down to circle lake, up to Spearhead shoulder, down and across Spearhead Glacier to Husume.
Encountered 15-20 cm of new snow on all slopes, with some wind affect on S facing slopes below spearhead shoulder, also noticed a thin 2cm sun crust developing on steep solar aspect during the skin up to Husume.
The spearhead glacier is still extremely thin in many areas. There are thinly bridged crevasses below guides notch, and Don't Swill. As well as a large band of open crevasses below spearhead shoulder. While approaching Husume we probed our way over a series of thin bridges just past the boulderfeild.

Winter on blackomb glacier
First time up blackomb backcountry this season and there is hope for 2024! We found about 15cm of new light powder above 2000m which remained cold and mostly unconsolidated with little wind affect throughout the day. New snow resting upon supportive wind affected snow from the previous storm cycle, making for really nice turns on lower angle slopes. Still a bit thin on body bag so we exited back down the glacier.

Cowboy Ridge
Staying at K&C hut for a few days. Toured around on top of Cowboy Ridge and the Coral area. Beautiful day up there but snow was very wind affected. Did a couple laps down to Singing Pass looking for better snow in the trees but was very deep and heavy.

Disease Ridge slide
Fairly West facing. We knew there was a risk of the slope sliding, but did not think it would be so far down the ridge to rider’s left. Chose this line because there is a cliff on the right, to turn around and get out of avi path if it slid. It popped on my 1st turn, pointed it straight and then right out of the way. Yes we were aware of the Terrain trap at the bottom.

Disease Ride Powder Laps
Skinned from 7th up to Disease Ridge. Throughout the day we noticed an increase in temperature, with S facing slopes getting heavier though the day. We primarily skied the slope next to the first rock garden as it was shaded and stayed dryer and lighter snow.
Our group also intentionally dropped 3 small cornices part way up the ridge, with no avi's triggered on the slopes below. Mini-fridge sized chunks did make it most of the way down the slope.
We did notice a few cracks forming along some cornices, and we stayed away from those.

Rider accidentals Mid-Disease
Total of three skier accidentals noted on northerly aspect of Mid-Disease Ridge. Two released as Storm Slabs <24hrs old and one resulted from a cornice drop/slide in. All size 1. Slope varied from 38-30 degrees. Start zones were deposition zones near ridgetop with dry cold storm snow over a firmer old snowpack surface.
Climbing routes were all up known performers, and avies did cover tracks.

New snow (2-5cm at probe site) is heavy, saw some wind effect on Flute summit. Skis OK at 2000m, but drastically becomes isothermic below 1800m. No pit, but probed two crust down 30 and 70. HS ~90cm at 1850m. Pretty rough out there!

7th Heaven Snow Report
Quick observations
* anything under 1800m is effected by thaw and freeze cycles
* 1800 to 2000. Okay riding quality. Changes from dyst on crust to soft snow to crust/hard pack
* snow quality better over 2000m. Very low vis was a challenge
* conditions very similar to the weekend before with the main change that the lower part changed from heavy wet snow to a bumpy, crusty ride.
* snow depth between 55 cm in exposed areas to 100cm in sheltered areas
* sheltered, open trees offered the best riding quality
* no signs of recent avalanche activity

Singing pass and cowboy ridge
Did some coyboy ridge laps. Lots of pin wheeling. We decided to try singing pass on the way out. The upper section was not bad. The middle section had little to no snow. We walked for about 2km until it was ridable again. Definitely some more snow is needed before we do it again.

Disease Ridge
The snow depth was 70-100cm along disease ridge depending on wind transport.
Throughout the day there was little to no wind, so we found the 5-10 cm of new storm snow was not very cohesive or slabby.
Bellow the new snow, there was a very weak crust covering a 10-15cm layer of snow that was variable in its cohesiveness. In some areas it was weak, not dense and hard to move with quick hand pit tests.
When we had visibility we dug some hasty pits in the upper north facing slopes to assess that the upper lines into the bowl were safe to ride. However, the weather moved in and visibility quickly dropped. Due to the exposed rock and refrozen avi debris hazards we decided to not enter the bowl in white out conditions. We descended on the ridge through soft snow and breakable crust.

Singing Pass
Skined up Singing Pass; 2-10cm coverage made it barely skinnable. Up to 10cm where there's less tree coverage down to 2cm where there was more dense trees. Plenty of rocks, bare sections, and flowing water at most of the creeks as well but got away with only needing to take off the skis 6 times to cross these features. Was raining up to 1900m and the skins got very wet and glopped frequently. Skiing was miserable with heavy wet snow. No avalanche activity noted other than explosive avy control heard throughout the valley and plenty of snow falling from trees.

*Snow depth variety from 50cm in exposed areas to 95cm in sheltered areas.
*15 to 30cm of mostly wet snow sitting on a crust. Crust thickness varies
*New snow was easy to sheer of crust especially on steeper slope sections.
*No penetration through crust while riding.
*Rain/snow line varied between 1600m and 1900m through the day. Heavy pow turns above 1800m. Soaked slow snow below 1750m. Still a lot of hazards: rocks, roots, small trees.

Fitness lap
Headed for flute east and oboe via oboe traverse / moose meadows. After observing several large whumpfs on our up track (presumably on the recent SH layer) and battling with ridiculous glopping (photo is of skins with BD globstopper wax applied!), we decided to call it a day and turn around at about 1800m. We also saw several avalanches that ran in flute bowl from explosives. Did not get close enough to investigate (ongoing avy control).

Wedge Winter & Summer Trails
Here to report the wedgemount lake trail is bad. Couloir is in but not skiable/skinnable to and from the lake.
The entirety of the trail is not skinable save the top half of the winter FSR portion before the Dam. This zone is entirely not skiable yet all the way to/from the lake. Someone had to go look and it was us lol. Definitely wait for more snow before heading up this way unless you want to suffer. If you did put in the effort to swim through the rocks and crust, Rethel Couloir definitely goes but leave double the time you expect for the ascent and descent! We bootpacked to just before the lake with full ski gear, gave up and booted out and it took us about 7 hours.

Disease Ridge
A lap up disease ridge. Conditions started calm until ~11am when wind and snowfall picked up. 10-20cm of new snow on a thin breakable crust when skied but will definitely increase as this storm continues. Wind affect is VERY noticeable on lee slopes as many shooting cracks were observed; small sz1 wind slabs were set off as well. The thin crust was present at all aspects and elevations observed (up to at least 2100m). Crust+thin snowpack made skiing not very pleasant.

Dust on Crust
Skied Harmony bowl. It was 10-15cms on the raincrust from Tuesday. The crust is very firm and slick in steeper terrain but also carries well so we were slightly less afraid of hitting rocks (but still pretty afraid.) The sluff was running fast and loose out of the chute we skied. The exit out was fairly skied out so hard to say if the breakable crust 1600m from the other MIN yesterday still exists or not.

Fun day meadow skipping.
We found 10-15cm of soft, unconsolidated power along with 2cm+ of new surface hoar growth. This sat on a thick supportive crust from the Monday AR event, with large runnels visible even above 2000m.
Steeper NW slopes and most convexities had slid at the start of the week, with crowns and debris still visible. No sign of recent avy activity.
We avoided anything below tree line for fear of running into sharks, but found coverage in the alpine to be decent.

Below 1700m crust becomes breakable and much more challenging skiing.

Cowboy Ridge/ K&C hut
We skinned up Singing Pass on Saturday Dec 2 (skis on the whole way, encountering several sections of very light snow coverage) to K&C hut. With over 30cm of fresh snow overnight, we noticed recent releases up to size 1.5 on south facing steeper aspects of Cowboy ridge near ridge. Those breaking trail also noticing shooting cracks. On Sunday we woke up to a mild storm, high winds, and low visibility and chose Singing Pass for our descent. Mellow slopes and some tight trees provided fresh lines while steeper slopes exhibited more shooting cracks, whumpfs, storms slabs and wind slabs present. Sastrugi on Cowboy ridge visible from the trail on our descent. Warming at lower elevations and several sections of bootpacking on the way down over thin coverage.

Blackcomb Glacier
Blackcomb mountain, specifically Horstman and Blackcomb glaciers on Friday: Snow coverage ranged from 60cm to 0cm on glacial ice on NE to NW aspects from 2280m to 2040m. Recession on Blackcomb glacier is prominent and open crevasses were observed. A natural anchor and rope was used to rappel on to the glacier and to climb back out. Skiing was variable with an average of 10cm faceting low density snow on top of a melt-freeze crust, as well as exposed ice. Small surface hoar 3mm was seen at 2050m on Blackcomb glacier.

Heavy wind affect in exposed terrain on most aspects. A bit down from ridge top you can find good faceted snow and surface hoar to link some gentle turns. Lots and lots of hidden rocks. HS around 60-80cm and widespread surface hoar in sheltered terrain. Almost all creeks are open and skiing in tree covered areas looks almost impossible with almost no snow cover.
