During a break from skiing today at Bolton Valley, I took a short walk around the Village and remarked at how the snow is piling up as we move toward mid-December.
It’s a busy weekend for me and I wasn’t certain if I was going to get out for turns, especially since I was unsure if surfaces were going to be soft with temperatures in the 30s F, but comments about the great snow in the New England subforum at American Weather helped tip the balance. If we’d had a notable thaw-freeze, then 30s F probably would have cut it with respect to softening things up, but the snow hasn’t really cycled above freezing for a while – it’s already in such good shape that it doesn’t need to soften. With the next storm moving in soon to make the weather more questionable tomorrow, today also seemed like the better day to hit the slopes. That aspect helped motivate us to get out while the weather was relatively stable.
E and I headed up to the mountain in the midafternoon period, and we were a bit leery about parking because the snow report indicated that Bolton had already filled their upper lots and people were parking down at Timberline. We were late enough that plenty of spots were opening up though as others finished their day and headed home.
The resort is definitely humming as they start to move to every day operation this week. They had all the lifts going except Timberline, where I don’t think they’ve made much snow yet, and the natural depths down at 1,500’ aren’t quite there to support lift-served traffic. Patrol has opened up just about everything else though – low angle, moderate angle, steeps, trees, people are skiing it all. Some steep, and even moderate natural snow terrain requires various levels of negotiation around the usual patches depending on whether you’re using rock skis or not, but you really can ski just about anything.

The snow quality we encountered was fantastic, soft and carvable but not sticky at all, and there’s no ice anywhere to speak of because of the huge resurfacing we got from those recent storms. The resort has all of Wilderness open with zero grooming, so they’re just letting people have at it as nature intended. That means that there’s plenty of uneven terrain and occasional water bars to negotiate, but the snow quality is so good that it’s simple to deal with any obstacles you encounter.
Dylan was up with a bunch of friends from UVM, so while we were waiting to meet up with them at the bottom of Wilderness, I walked around the Village a bit and grabbed some additional photos. It’s been a few days since the last storm, but there’s tons of snow all over the place up there that’s piled up and sticking to things. The snowpack is certainly in good shape for early December. We’ll soon see what this next storm does for the slopes – Winter Storm Warnings are already up as it approaches.
Winter Storm Warnings are already up in our area ahead of the next big wintry system that is expect to impact the area.
A light in the Bolton Valley Village reveals evergreens caked with snow from the most recent storm to hit the area. The Village was teeming with skiers this evening setting out for ski tours with their headlamps to enjoy the fantastic snow conditions
I was busy through most of the afternoon, but still wanted to get out to the mountain today to check on the additional snow that fell on the back side of our most recent system. As the temperatures dropped yesterday, the density of the snowfall fell to 10% H2O by the afternoon, and finally down into the 3-4% H2O range overnight. Bolton Valley was reporting another 5 inches of accumulation as of this morning, and that drier snow atop the substantial amounts of denser snow from the earlier part of the storm would likely set up some excellent turns.
Since I was starting my tour around dusk, I fired up my headlamp because I knew I’d need it on the descent. What amazed me this evening was the number of people who were out touring by headlamp as well. I knew that folks got out for Wilderness tours after dark because I’d sometimes see them on their way up when I’d be finishing a late descent, but I had no idea just how substantial the numbers were. During the course of my relatively short tour this evening I saw at least a couple dozen skiers out there for headlamp touring, and most of them were actually ascending or just starting out at the parking area. Indeed, the Village parking lot was teeming with skiers, more than I’ll typically even see for a morning session. I guess that part of local ski culture is clearly alive and well. And I can’t blame folks for getting after it this evening, it was dead calm with temperatures in the 20s F with new dry powder atop a substantial base. I can remember a couple decades ago when folks would need to set up these elaborate, heavy battery packs to run their powerful halogen lamps to have enough light for skiing at night, and that all seems pretty irrelevant now with modern LED headlamps. My little LED headlamp was more than powerful to enough to provide light for me to ski, even on its lowest setting. I did use the brightest setting on the descent since I figured I might as well, and it was potent.
In terms of the snow, with settling I generally found 2 to 4 inches of the new drier snow in the 2,000’ to 2,500’ elevation range. In some spots it was easier to distinguish the demarcation between this drier snow and the denser snow below as I probed around, but at higher elevations where even the base snow was drier, it became more and more difficult to separate the new snow from the old. In any event, the quality of the skiing took a nice notch upwards with the addition of the new powder. I’m sure the earlier snow dried out a bit as well, but with this new snow on top, turns were much silkier than yesterday, and lower angle terrain was much more in play and enjoyable since you were gliding through fluff instead of sinking into the denser stuff. There’s excellent midwinter skiing to be had out there right now in the Northern Greens, whether you go during the day… or at night.

Today on Fanny Hill at Bolton Valley – the snow just keeps falling, so we’ll keep making turns!
Of the 11 winter storms we’re recorded so far this season at our site in the Winooski Valley, 3 have delivered more than a half inch of liquid equivalent, and they’ve had a notable upward trend in L.E. The November 21st storm brought 0.72” of L.E., the November 26th storm brought 1.14” of L.E., and this most recent storm that began on December 3rd brought more than 1.40” of L.E., with snowfall continuing tonight. These storms have really helped to build the mountain snowpack, and the snow depth at the Mt. Mansfield Stake is now more than a foot above average.
The snow just continues to pile up in the Bolton Valley Village with these weekly larger systems and the smaller ones in between.
Bolton Valley was reporting another 14” of snow in 24 hours, and I popped up to the mountain this afternoon to check it out. Elevation has had quite an impact on the snow from this most recent storm, and the snow depth profile coming up out of the Winooski Valley is quite extreme. There’s really no snow at the base of the Bolton Valley Access Road aside from leftover piles, and it’s like that all the way up above 1,000’, and then the depth begins to ramp up. Here’s the snow depth profile I found on today’s ski tour:
Folks up in the Bolton Valley Village are constantly having to clear the snow with storm cycles frequently affecting the area in the past few weeks.
It was more challenging to get depth readings in those upper elevations since the pack is getting pretty deep and there are a lot of different layers with varying consistencies, but that general trend I’ve seen on the mountain recently of almost an inch of depth increase per 100’ of elevation gain seems to generally be holding. The depths I was getting at 3,000’ also seem generally in line with the current reading at the Mt. Mansfield Stake of 33” at 3,700’.
I arrived up in the Village in the early afternoon to a maelstrom of huge flakes coming down in association with the back side of the storm system, so the mountain continued to tack on more to the snow totals. Fat skis were unquestionably the play for today. The accumulations from this storm definitely came in denser than the previous one, and while fats were of course great for stability, they were also really nice for planing on lower angle slopes and getting additional turns out of that snow. Even though you were only sinking maybe 6 to 10 inches into the powder because of the density, it was still slow going if the slope angle got too low. Steep slopes indeed offered the best turns, and the base is so dense and deep that even on those pitches there’s not much to worry about in terms of coverage on the upper mountain.

Catching some turns on the Sprig O’ Pine trail at Bolton Valley this afternoon during heavy snowfall from our latest winter storm
Down here in the valley at 500’ our precipitation has generally been snow, but the temperatures have been marginal, so thus far we’ve had less than an inch of accumulation. It’s been a different story at elevation though. We’d been watching the Bolton Valley Base Area Webcam since this morning, and more often than not it’s shown moderate to heavy snowfall with some big fat flakes. Even from the webcam you could tell it was accumulating, so I waited until the afternoon to let some of new snow build up, then I headed up to the mountain for some runs.
Coverage has mostly melted back at the base of the Bolton Valley Access Road at 340’, and the precipitation there was a mix of rain and wet snow, but cars coming down from the resort had at least a couple inches of fresh snow on them. As I ascended, somewhere in the 1,000’ to 1,500’ range, the precipitation instantly flipped to 100% snow, and you could tell that you’d hit a critical temperature threshold. Up in the Village at 2,000’ it was pounding big flakes. There were visibility issues just like yesterday, but while yesterday was due to thick low clouds and fog, today it was due to the snowfall.
A view of the main base lodge at Bolton Valley – heavy snowfall greeted me as I arrived up in the Bolton Valley Village for some afternoon skiing.
Like yesterday, I skied again off the Mid Mountain Chair, and you could tell that the base snow had stiffened up where it had been groomed, at least up around 2,500’. From about 2,200’ and below, there was a notably softer base. At those higher elevations where the base was starting to tighten up, the new snow was definitely helping to take the edge off, but with on piste skier traffic, the fresh snow had been pushed around a lot, and you had to move off the groomed terrain to really take the best advantage of the new snow. In areas that hadn’t been groomed, there was no demarcation between the new snow and more recent layers below it, and my off piste adventures generally yielded turns in 12-14” of powder. The powder did get a bit denser as you dropped in elevation, but it was still quite manageable. I was on mid-fats and never even felt the need to switch to alpine turns; the snow was dry and consistent enough that Telemark turns were still comfortable all the way.
Heavy snowfall continued up at Bolton today throughout the afternoon while I was out on the mountain
The freezing level was slowly dropping in elevation while I was out on the mountain, and by my last run it was only right down at base elevations where the groomed base still had that initial softness I’d encountered. Driving down the access road at closing time was a bit hairy with the pounding snow and fresh accumulations. The road accumulations finally started to abate around 1,500’, and road surfaces switched to just wet below that. The snowfall rate was easily an inch an hour at times, and even thought it occasionally slowed down for periods earlier in the afternoon, it looks like it averaged around that inch per hour mark because the resort was reporting 4 inches of new snow as of 4:00 P.M. closing. If the snowfall keeps up for a while this evening like it did this afternoon, they’ll have another great shot of snow to cover up the slopes by the morning.
E glides through some of the soft snow that met us up at Bolton today, with temperatures in the 30s F and low clouds for very December feel
With temperatures in the 30s F today, I was unsure if snow surfaces up at the mountain were going to soften. Dylan was up at Bolton Valley with some friends though, and when we texted him for an update, he said that indeed the snow had softened up. With that news, E and I headed up for a few runs this afternoon. Visibility was near zero on the mountain with low clouds and fog, but it did give the mountain that low light solstice/holiday feel.
Indeed the snow surfaces were great. We’d waxed our skis pretty thoroughly just in case, but we didn’t encounter any areas of sticky snow, it was just buttery smooth spring-style snow that you could really sink an edge into. I’m not sure if the snow was stiffer up high, but we were just lapping the Mid Mountain Chair, and everything on the lower mountain was great. The Wilderness Lift was also open today, so the natural snow terrain that they’ve opened is still in decent shape. Those surfaces that have softened will of course tighten up when temperatures drop back below freezing, but hopefully the storm coming in to the area tomorrow will do a decent job of covering up the current base. There certainly seems to be the potential for a decent resurfacing of the slopes with an inch or so of liquid equivalent in the forecast.

Ty rides through some of the fresh powder we encountered today in Bolton’s Outlaw Woods
Last night we picked up another 4 to 5 inches of snow here in the valley from the weak cold front swinging through the region, and not surprisingly, the local mountains picked up twice that amount. Bolton Valley was reporting 10 inches of new snow atop the 15+ inches they’d received from the storm at the beginning of the week, and this new snow came in around 5% H2O according my morning liquid analyses. The new drier snow atop the base was a recipe for some great skiing.
Ty was off from work this afternoon, so we popped up to the mountain for a ski tour on Wilderness. Relative to the last storm, the Winooski Valley down by the base of the Bolton Valley Access Road did better with this event; whereas the coverage was somewhat patchy after the last storm, it was generally continuous with a few inches present this morning. I checked snowpack depths during the tour as usual, and it’s getting tougher to get measurements as the snowpack gets deeper, but with settling through the afternoon, depth increases seemed to be as follows relative to what I found yesterday:
So essentially, the snowpack depths I found today were about 500 feet lower in elevation than equivalent depths I found yesterday.

The Wilderness Uphill Route had seen plenty of skier traffic, and there was a dual skin track all the way to the Wilderness Summit that made conversation easy while we ascended. I was hoping to bring Ty over toward Fanny Hill again in line with the tour I’d done yesterday, but ski patrol had fenced off Upper Crossover. They really want touring to be confined to Wilderness, and I guess that’s not too surprising with the amount of operations they have going on Vista. With the amount of activity we saw going on all around the resort, it’s obvious that they’re going full tilt in preparation for re-opening on Friday with their partial-week schedule. I’m not sure how much of the mountain they’re going to open, but with the amount of natural snow out there, they’re going to have a lot of options.

In terms of the skiing, it was great. Conditions were already excellent yesterday, and now Mother Nature threw another 10 inches on top of that, so it’s about what you’d expect – lots of bottomless powder. We hit the Wilderness Summit just as sunset was approaching, so the views to the west were stupendous on such a fine afternoon. With the snow remaining deep, you wanted to shoot for intermediate pitches and above for decent turns. Based on my experience from yesterday, we did have full fat skis today, so that helped a lot with floatation and the ability to turn on those lower-angle slopes a bit more.
Adding a set of tracks to Fanny Hill while out on a ski tour at Bolton Valley today – thanks to the remnants of Winter Storm Cait, Bolton was reporting 15 inches of new snow, and it had sufficient density to ski even the steepest terrain.
Tuesday: We are still reeling from the season’s first big snowstorm that smothered the northern Green Mountains in a heavy blanket of prime base building snow Sunday night to Monday morning. In addition to the 12-15″ we woke up to Monday morning, it appears we’re in for another 1-3″ today here in the upper elevations and – perhaps even more importantly – the return of cold temperatures on the ol’ “wet bulb” to fire up snowmaking efforts again. As we get closer to Friday we’ll keep you posted on trails and lifts for this weekend, but perhaps needless to say, we will definitely be expanding terrain this weekend, including Snowflake Lift, a small buildout in the Hide Away Terrain Park and several trails making their season debut. Stay tuned on that front.
No lift service today, but we’ve gone ahead and opened the Wilderness Designated Uphill Route so you can get some fresh pow laps in if your schedule allows.
Based on Powderfreak’s comment from yesterday about skiing on just the top 4” of the snow, and the density of the snow down from my liquid analyses down here at our house, I brought mid-fats for today’s tour. I figured I’d be riding Sierra Cement, but that wasn’t at all what I experienced. I’ll mention more about the snow density after covering the storm accumulations and snowpack depths.
There’s a very impressive elevation gradient with respect to the snow accumulations from this storm. Down at the base of the Bolton Valley Access Road at 340’, there isn’t even complete coverage on all aspects – I’d call the snowpack there T – 2”. I didn’t monitor the snowpack too closely on my ascent to the Village, but coverage was certainly continuous by 1,000’. Up in the Village around 2,000’ or so, I found 10-12” of snow, and here are some measurements at elevations during my tour:
2,000’: 10-12”
2,500’: 15-16”
3,000’: 18-20”
As the numbers reveal, there’s a huge snow depth gradient above 2,000’ – you’re basically looking at the depth going up about an inch every 100’ of vertical. Now those numbers are for total snowpack depth because I’m not sure if I’d be able to distinguish exactly what portion came from this most recent storm, but much of it was from this storm (as Bolton’s summit storm total of 15” would suggest).
The Wilderness Uphill Route has a beautifully packed skin track in place at this point, so travel on the snow is easy. And getting back to that discussion of snow density, it’s not Sierra Cement. In the higher elevations, the density going several inches down into the snowpack is sub-10% H2O powder – I’d put it somewhere in the 6 to 8% H2O range if I had to guess. You sink well down into it, I’d say a good foot, and it’s nicely right-side-up. As I mentioned, I brought mid-fats, but fat skis are actually the tool you want (or a snowboard, etc.).

It was quickly obvious on my ascent that some decent pitch would be required for turns, so I toured all the way to the top of Wilderness. I checked out Bolton Outlaw, and it had seen enough traffic to track it up pretty thoroughly, so I continued on to Upper Fanny Hill and put the third set of tracks down there. I continued on to Fanny Hill proper and got probably the fourth set of tracks there. The powder skiing is fantastic as long as you’ve got at least intermediate pitch. Shallower than that and the powder is just too deep to keep decent momentum (and that’s another reason to bring fat skis because you can make use of that extra floatation).
In terms of snow quality, it’s as I described at elevation, and of course the overall depth decreases as you descend, but the quality stays high right down to 2,000’. Only just as you approach 2,000’ do you encounter any sort of snow quality issues, and there’s a slight crème brûlée crust in there a couple of inches below the surface where there must have been a bit of warming. At that elevation it’s still quite subtle and you can essentially ignore it.
As Bolton’s snow report indicates, the resort is considering expanding their open terrain thanks to this storm, and moving to some of the natural snow terrain is pretty obvious at this point. We’ll have to see which terrain can hold up to lift-served traffic, but I can’t believe there’s not more talk about this storm and what it could do for the start of the season. This storm was a total liquid equivalent bomb, and not only that, the snow is good to go. This storm was an absolute season-starter. Sometimes storms like this come in so dense or warm, that the tenor will be “This is going to be a great base as soon as we get some good snow on top of it”. Well, there’s no need to wait, the snow is already good to go, and it’s currently getting covered more with the snow from today. It’s not every day you get such a base-building storm that immediately offers up fantastic midwinter skiing. We didn’t even have to wait until December for this one – it somehow snuck in during November, which is another great bonus.
Ty was free this morning and joined me for some ski touring in the fresh powder up at Bolton Valley.
The mountain snowpack that had been building up over the first half of the month melted back somewhat in the middle elevations at the end of last week, but this latest winter storm seemed to have the potential to replenish it. As of this morning, we’d picked up roughly 4 inches of new snow composed of 0.6 inches of liquid at the house, so the local mountains should have added enough new snow to set the table for more low-angle touring in the powder. Bolton Valley was reporting 3 to 4 inches of new snow overnight, and 5 inches in the past 48 hours. Assuming a similar density of snow to what fell at our house, plus whatever snow was in place before, it definitely felt like it was worth a visit. I didn’t expect the snow quality to be outstanding enough to suggest that E or the boys should join me, so I expected it to be a solo tour. As I was about halfway through preparing my gear, Ty woke up and let me know that he was actually interested in getting in some turns before work, so that meant I’d have some company!
Some of today’s snow sliding off the windshield of a car as temperatures warm in the Bolton Valley Village
In the Winooski Valley at the base of the Bolton Valley Access Road, we found 1 to 2 inches of new snow from this most recent storm, and up in the Village, total depths were 4 to 5 inches. Temperatures this morning were around the freezing mark, with a mix of wintry precipitation types as we set out on our tour. We found that snow depths increased a bit with elevation, hitting 5 to 6 inches around 2,500’ and 6 to 7 inches where we topped out around 2,700’.
The powder skiing was decent, with snow that was relatively dense but not sloppy or soggy on the upper half of our tour. The density did increase a bit more as we descended back toward the base around 2,000’, but the snow still hadn’t progressed to that spring-style sticky stuff. I had freshly waxed up my skis in the morning, and that did appear to help give me an slightly easier time than Ty, who hadn’t waxed.
Folks had clearly been out having fun with all the new snow in the Bolton Valley Village
While today’s powder was decent, the snow I found while out ski touring last week was definitely superior. I think that last week there was a touch more base, the snow overall was a bit deeper, and most importantly, the snow was notably drier. All those factors came together to set that skiing above the quality of what we found out there today. This dense snow that we just received does have the water content to set up a more substantial base though, and it’s really going to be great with some additional rounds of snow on top. The models do suggest that there are some events in the pipeline over the next week, so we’ll see what the mountains get from those.
A frozen river view out on my tour of the Bolton Nordic and Backcountry Network today
I wasn’t exactly sure where on Bolton’s backcountry network today’s ski tour was going to take me, but my plan was to start with an ascent up to the start of the C Bear Woods, and then go from there. I haven’t toured in that part of the Network yet this season, but the ridgeline there tops out around 2,400’, so starting in the lower Village, it would give me a good sampling of the snowpack in the 2,000’ to 2,400’ elevation range.
For my tour back on Monday on some of the lower sections of the Network I topped out around 1,800’ and generally found 6 to 12 inches of powder, and the tenor of the powder skiing was that something with a bit more pitch would be appropriate for the snow depth. With continued rounds of snow accumulation over the past couple of days (and an additional 2 to 3 inches reported in the past 24 hours at Bolton as of this morning’s update), I figured the powder might even be a notch up from where it had been at that point.
It was midmorning by the time I arrived at the Village, and temperatures were very comfortable in the lower 30s F. Being the big holiday week, the resort was really humming, and they were already parking folks in the lower Nordic Center parking lot. That worked out well for me though, since it’s right on the Broadway Trail that links in nicely with the heart of the Backcountry Network.
A view during today’s tour down by the Joiner Brook bridge showing the snowpack from recent storms
Around 2,000’ in the open areas of the Village, the depth of the surface snow was quite variable between the effects of the wind and sun, but in general I found 5 to 6 inches of powder over a consolidated base. There wasn’t any obvious rain crust, but there was a denser layer below the powder. That layer generally wasn’t present in the trees, so I assume it was from wind and sun. Up at 2,400’ I’d say powder depths were about the same as what I found in the 1,500’ to 1,800’ elevation range on Monday, so between additional accumulations and settling, I guess things roughly held pat at that level. The pitches near the top of the ridge there are up in the black diamond range, and I think the uppermost parts of the ridgeline were a bit windswept because the snowpack wasn’t sufficient for confident turns in that area. Noticing that, I headed southward to the right of the main C Bear Woods entrance into some other areas of glades to shallow out my overall run. Intermediate pitches offered nice turns, and the snowpack easily supported that type of skiing. The best turns of that descent were in the lower slopes among the moderate and lower angle pitches as I got back toward Brook Run.
I’d left the option open to extend my tour up toward some of the Bryant Trail terrain, but it was approaching midday and the powder was already started to get denser and a bit sticky as the temperatures pushed above freezing. As I headed to the main base area, it was turning into a fantastic day with breaks of sun and temperatures moving into the 30s F. That’s a pretty nice combination for the holiday visitors to have comfortable temperatures and some decent snowpack, and it will be interesting to see how this holiday week plays out overall for visitation at the local resorts. It’s been pretty sweet to have some daily refresher snowfalls recently to bolster the snowpack, and the snow reports I’ve seen from the resorts around here have indicated that it’s been allowing them to continue to open new terrain and expand the trail count. Visitors to the slopes should generally be treated to some comfortable temperatures for the remained of the holiday week, which I think many would take over the subzero spells that can often occur around the start of the new year. It looks like anyone going out on Sunday might have to dodge a bit of rain though based on the current forecast.
This may be one of the nicer holiday week’s we’ve had recently in terms of the quality of the skiing. Looking at my notes, I’ve had a half dozen backcountry ski tours in about the past ten days, and that’s pretty decent because sometimes the backcountry doesn’t even get rolling until January or February. On average, it should get going (at least on low and moderate angle terrain) in mid-December here in the Northern Greens, but the past three seasons haven’t hit 24 inches at the Mt. Mansfield Stake until January. Technically, the stake only hit the 24-inch mark for the first time this season on Tuesday, but it’s been hovering in the 20-inch range since mid-month when Winter Storm Diaz hit, and the snowpack came together in such a way that those 20-ish inches were sufficient to put a lot of the local backcountry terrain in play for quality turns.

Enjoying some of the snow on the evergreens along the route of my backcountry tour today
I hadn’t been out to the mountain since Winter Storm Elliot finished up, and although it was a mixed system in terms of precipitation, I was encouraged by how it played out for the local snowpack. The storm brought roughly 8 inches of snow to our place down in the valley, and represented a net gain in both snowpack depth and snowpack liquid equivalent. Bolton Valley was reporting 12 inches of new snow from the system, so the mountains must have fared at least as well as the valleys.
With some rain during the middle part of the system, I was wondering about the condition of the snow surfaces, so today I decided on a relatively low angle tour on the Bolton Valley Backcountry Network to get a feel for how the new snow had settled in. I started at the Catamount Trail access point on the Bolton Valley Access Road, which is down around 1,200’, and toured up to around the 1,800’ elevation a bit above Caribou Corner. Those are relatively low elevations overall, and 1,200’ is below even the Timberline Base, so it would certainly be a challenging stress test to speak to the quality and utility of the snowpack.
At 1,200’ at the parking area I found about 4 to 5 inches of powder above the base snow, and most notably, I couldn’t really find a rain crust. There was a clear demarcation between the consolidated base and the surface snow, at least around the parking area where the snowpack is a bit more exposed to snow maintenance and sunshine. The depth of the powder quickly increased as I ascended, and by about 1,500’ I was easily finding 6 to 12 inches of powder. It became hard to judge the depth of the surface snow though, because I typically couldn’t even find an interface between the new snow and the underlying snowpack; the wetter precipitation from the storm must have either drained well or transitioned smoothly to snow. I’d say total snowpack depth was probably around 10 to 12 inches at 1,200’ and 12 to 16 inches at 1,800’, but there’s plenty of substance to it, so it’s quite skiable up to moderate angles in maintained areas, and obviously it’s going to be notably deeper up above 2,000’.
A snowy view of a cozy cabin along the route of my ski tour today
In terms of the skiing, the powder was actually too deep for the lowest angle sections on the tour, and I’d have to use existing skin tracks or other skier tracks to maintain or pick up speed. The next tier of pitches skied great with the snow though. I typically like that tour up to Caribou Corner when there’s about 4 to 6 inches of powder over a consolidated base, so this really was a bit deeper than that, and I’d say folks should move on up to moderate angle terrain for the best backcountry turns, especially with additional snow falling over the next couple of days. There was light snow falling during my tour in the form of those big fluffy flakes, and I see that the resort reported an inch of new this morning.
The season snowfall seems roughly on track at our house observations site as of Christmas. Snowfall to date on the 25th was 40.1” vs. a mean of 40.4”, and snowpack depth at 10.5” was a few inches above average. The SDD for the season were a little behind average pace at 146.5 SDD vs. the 162.2 SDD average. I can see in the data that the SDD deficiency is largely due to that slow first half of December, because we were still ahead of average SDD as of the end of November, and then the pace started to fall off before picking up again in the second half of the month.
