Ty diving through the powder on today’s tour as we descend in Bolton’s Snow Hole area
Based on the quality of yesterday’s skiing, I was leaning heavily toward heading out for another tour today. The backcountry conditions around Bolton are already quite good, and they were reporting another 2 to 4 inches of new snow this morning, so that was a nice bonus. Temperatures were expected to be about the same as yesterday, which meant single digits F.
Ty was able to join me today, so it was great to have company, and we were able to get some actions shots in the powder. We did a tour somewhat similar to what I did yesterday, but we lengthened it out a bit more. Instead of heading up to Heavenly Highway and working our way down to North Slope, we went all the way up to Moose Glen and then wrapped around on a descent toward the glades around Snow Hole, which was roughly a four-mile tour. I chose that route to get us some relatively high altitude turns after observing the notable improvements in the overall snowpack above 2,500’ yesterday.
The number of visitors at the resort seemed a bit less today – there was no sign posted about the Village lots being full, and we easily grabbed a parking spot in the upper lot by the entry to the Backcountry Network. With cold temperatures preserving the snow, conditions were similar to yesterday with 1 to 2 feet of powder available wherever wind hadn’t scoured it to lower depths. Touring some of the higher elevation trails allowed us to see the various areas that had been hit by wind, and you just had to be cognizant of where winds had affected the snowpack to pick the lines with the best undisturbed powder. The middle elevations were much less disturbed by the wind, and you could pick just about line and get some great powder turns.

The models suggest we might have another long-duration system like this past one starting up tomorrow night and running right through the week, and I see that Winter Weather Advisories are already up for the Northern Greens in anticipation of some of that snowfall.
The powder is great and the backcountry ski traffic has generally been light – as I passed by, I saw just one old set of tracks in the Cup Runneth Over area.
Our current storm cycle started up back on Wednesday, with low pressure deepening as it passed over southeast New England and up into Maine. It then headed on up into eastern Quebec, stalled there for a bit, and finally moved to northwest to James Bay, where it’s expected to sit until about Monday. While this isn’t a stacked low-pressure system sitting in the Canadian Maritimes feeding continuous 1+”/hr. snows into the Northern Greens, the broad cyclonic flow supported by the various positions of the low pressure has kept the area in a nice moist westerly/northwesterly flow that’s been feeding snow into the mountains. So, this isn’t a typical 24-, 48-, or 72-hour type of storm cycle; it’s a much more drawn-out sort of “cycle”. I wasn’t sure how the positions of this low would actually play out with respect to snowfall, but since well before the start of the storm the National Weather Service Office in Burlington has been on it – they felt that the potential was there for solid amounts of snow over the protracted period. And they certainly weren’t wrong. It’s been a little tough to total up the mountain accumulations for the full event because it’s already been going on for four days, and the resorts typically only report up to 48-hour accumulations, but it looks like anywhere from roughly 1.5 to 3 feet have fallen in the Northern Greens from the system as of today.
Bolton Valley was reporting 4 to 6 inches of new snow overnight on top of their previous accumulations from the system. I’d already been finding snow accumulations of 9 to 10 inches when I was out touring at Bolton on Thursday, so between whatever fell Thursday night into Friday, plus these additional Friday night accumulations, there seemed to be some good powder potential out there. Temperature forecasts for the mountains were in the single digits F today, so touring seemed to be the best option. E was initially going to join me for a ski tour, but after thinking about the temperatures for a bit, she ultimately decided to work out at home instead.
I headed up to the mountain a bit after noontime, and people certainly didn’t seem to care about the temperatures – the signs were up for visitors to park at Timberline because the upper lots were full. Being after noon, I knew I’d be able to get a spot from someone who was leaving for the day, so I headed up to the main base anyway. I still ended up getting a spot in the lowest tennis court lot though, and that changed up my touring plans a bit. I had initially planned to ascend at the start of the Wilderness Uphill Route and then make my way toward Gardiner’s Lane, but since I was parked right down by the Pond Loop area with easy access to the Bryant Trail, I ascended there instead. I had just planned to loop around Bryant Cabin and then head out to start my descent on North Slope, but the temperatures felt great while touring, so I continued on up to Heavenly Highway, topped out around 2,800’, and started my descent via the “Not a Trail” glade. From there I continued down North Slope and then made a second ascent to ski some of the glades in the Snow Hole area.
Up above 2,500′ there were frequently areas with 24 inches of powder atop a substantial base for what must have been a snowpack depth in the range of 40 inches
It was clear that powder depths had increased at the resort since I was last there on Thursday. Winds have died down substantially now, so measuring the snow is much easier, and right at the car at ~2,000’ I was getting 8-12” depths for the surface snow above the base. By 2,500’ the typical depths were in the 12-16” range, and around 2,800’ I’d say they were 12-18”. I’d still think that’s somewhat conservative though, because I was often finding powder depths of 24” up around 2,700’-2,800’. Right now, getting up above 2,500’ makes a real difference in the snow though, because those areas must have done really well during our previous warmup – the interface between the surface snow and the base has mostly disappeared by that point (making it harder to measure just the new snow), and the skiing is really good. Dropping into my initial descent, I could tell that the overall snowpack was really deep. Below that top 24” of powder there was substantial base, and I’d say the snowpack there has to be 40 inches. The snowpack at the Mt. Mansfield Stake was at 39” as of a couple of days ago, and it hasn’t been updated since then, but based on what I found out there today a few miles to the south, it’s got to be over 40 inches by now.
Anyway, I’d recommend doing most of your touring up in that 2,500’ to 3,500’ elevation range if you can – it’s just a notable improvement in the overall snowpack below 2,500’. It’s still nice skiing down there, but it’s sort of mid-fat powder conditions below 2,500’, and full-fat conditions above 2,500’. I toured on mid-fats today, but I was wishing I had fat skis in that deep snowpack above 2,500’. The powder is of medium weight, so there’s plenty of liquid equivalent in there to really keep you off the base. As of this evening we’re approaching an inch of liquid equivalent from this system at our site in the valley, so you know the mountains have had at least an inch of two of liquid equivalent from this system so far, and it definitely felt like it based on what I experienced above 2,500’ today.

With respect to the ongoing storm, there was generally light but consistent snow falling when I was out on the mountain today. The flakes were small, in the 1 to 2 mm range, so it was hard to gauge snowfall rates, but I had to clean a decent layer off my car when I got back to it after just an hour or two of touring. Toward the end of my tour, the flake size was picking up noticeably to roughly 2 to 8 mm flakes. Down here at the house, we’ve had light snow all day, but it’s picked up more this evening with larger flakes, especially when strong echoes come through as more pronounced shortwaves embedded in the overall cyclonic flow move through the area. Based on what we’ve been seeing here at the house this evening, there should be at least another few inches out there by tomorrow morning for the mountains.
Snowdrifts were certainly on the menu during today’s ski tour. Howling winds from the upslope portion of our current storm cycle have pounded the Northern Greens and whipped up the snow into formations 5 to 6-feet deep as my buried ski pole can attest.
Our anticipated long-duration storm system began in the area yesterday with some light snow accumulations for the mountains and valleys, but snowfall really picked up overnight, so I decided to head up to Bolton today for some turns. As of this morning, Bolton Valley was reporting 7 inches of new snow from the storm, and snowfall has continued today. Their reported storm total seemed like a good amount for some ski touring, so that was my plan if I was heading up to the mountain alone. Dylan didn’t work until the afternoon, so he was planning to head up for a morning lift-served session with his fried Parker, and E had the day off due to school closures from the storm and she was thinking of going as well. Those plans fell through though – the winds were so strong that the Vista Quad Chair was on wind hold before it ever opened, and even the Mid Mountain Chair quickly went on wind hold in the morning. The only chairlift running by mid-morning was the Snowflake Chair, and with most of the Snowflake terrain not open, we generally felt that it wasn’t worth heading up for such minimal terrain. That brought me back to my original plan of ski touring on Wilderness.
Down at our place in the valley we’d picked up 4 to 5 inches of snow from the storm at that point, but the contrast in accumulations was stark as I dropped down into Bolton Flats on my way to the mountain – the snow accumulation there looked like an inch at most. Accumulations were the same at the base of the Bolton Valley Access Road at 340’, and I had to get above 1,000’ before I really started seeing accumulations of at least a few inches. Up in the Village parking areas, it was impossible to find a sheltered spot to get a reliable measurement of accumulations at 2,000’, so I had to wait until I got into the relative shelter of the Wilderness Uphill Route to really check the snow depth. Once one the ascent though, I checked the snow depth along the sheltered edge of Wilderness numerous times, and the measurements were all between 8 and 9 inches, with one measurement of 7 inches. At 2,500’ I was measuring 9 to 10 inches of accumulation, and I never got any reliable measurements higher than that, even up above 3,000’. I stress “reliable” because the winds had wreaked havoc on the snow in many areas. Some spots were scoured down to the old base, and some places had 5-foot drifts. Up at the Wilderness Summit at 3,150’ the winds were absolutely howling – they had to be in the 50 to 60 MPH range at times. Finding a sheltered spot to pack up my skins was a huge challenge. Thankfully, temperatures were in the 20s F, so there wasn’t frigid cold to go with those winds. Photographs of gentled-settled powder snow were difficult to come by today, but if you wanted to get images of drifts… they were everywhere.
Oh those drifts out there today! Even down at the Village elevations, the wind had sculpted the new snow into all kinds of formations and covered objects in many different ways.
Here’s the snow accumulations profile I saw as of midday in the Bolton Valley area for this ongoing storm:
The skiing turned out to be excellent though. As long as you avoid any wind-scoured areas, there’s been a really decent resurfacing from this storm so far. We’ve picked up ¾” if liquid equivalent from the storm at our site down in the valley, and the mountains should have had at least that much, so an inch of new liquid equivalent up there seems very reasonable based on what I experienced today. The new snow our there certainly wasn’t fluff; with all the wind, it was actually feeling like typical 10% H2O synoptic snow, and out of the wind, the new snow was substantial enough to even resurface black diamond pitches. So, while it wasn’t sublime champagne powder, it was decent medium-weight powder, and it was much more what the slopes needed with respect to resurfacing.
We didn’t get too much accumulation (about an additional half inch) during the day today here at our house along the spine because as forecast, the Froude Numbers went well above 1.0, but they may have come back down a bit because we’re getting some decent accumulation this evening with these more recent bands of moisture pushing through.

With warming temperatures in the forecast today, I figured the slopes would be softening up, so it felt like a good day for some lift-served skiing. Temperatures were still well below freezing this morning though, so I was unsure how quickly surfaces would soften, and I decided to sharpen the edges on my mid-fat Telemark skis. Last time I really seemed to need edges earlier this month, I found them sorely lacking, so it felt like it was time. I can’t recall the last time I sharpened the edges of those skis, but it has to have been at least a couple of years
Out on the slopes I found an interesting mix of conditions. We’ve had some mountain temperature inversions in place recently, so I actually found some of the softest conditions up high near the summits, while groomed slopes with manmade snow were notably firmer on the lower mountain. While there was nothing that was outrageously icy, it was nice to have the extra sharpness to my edges on the manmade snow.
One exciting thing I saw in the Bolton Valley Snow Report this morning was that resort had finally opened up the Cobrass area, which included Cobrass and nearby trails like Preacher, Devil’s Playground, and Cobrass Woods. Today being my first chance to check out the conditions in that area, I headed right down Cobrass for my first run. Being up near the summit where the warmer temperatures of the inversion had been around for a bit, I found that the snow on Cobrass had already softened up nicely. The skier’s right of the steep upper section had excellent soft snow that had been built up by skier traffic. It was so good that I went right back to it on my next run. I also hit Alta Vista off the Vista Summit, and it was nice, but it didn’t offer up quite as much soft snow as Cobrass.
Fun snow shapes were starting to appear today as the recent snow softens and begins to move around.
We’re moving out of the quiet period of weather that we’ve had over the past several days in a more active regime. The system moving into the area over the next couple of days doesn’t look like it will provide any snow, but the one behind it should give the local mountains their next shot at substantial accumulation, with the potential for upslope snow on the back side.
E joined me for today’s ski tour in that excellent Timberline powder.
I’ve been telling E about the fantastic powder conditions I’ve been finding on my outings up at Bolton Valley, so today she joined me for a ski tour. I returned to Timberline and brought her on the same tour that I did yesterday, and the powder continued to be just as fantastic as it’s been the past several days. She was definitely impressed with the quality of the powder, and we talked a lot about exactly what was making it come together for such perfection and effortless turns. It came down to the fact that the gradient in it is just ideal; it’s right-side-up with no intervening hollow or dense layers. The top also has a subtle layer of extremely delicate surface hoar, or surface hoar-like crystals, and that really finishes off the uppermost layer of the powder with extremely dry snow to set the starting point of the density gradient. Anyway, the turns were silky smooth, and the skier traffic was very light, so there are still plenty of fresh lines out there for folks who want to check out some really primo powder. Tomorrow might be the last day of this current weather regime though, since some warmer temperatures are coming. Our next potential snowstorm could be coming in just a few days though; the models suggest there could be something around the New Year’s holiday.

High-quality powder snow is generally ephemeral; it’s best skied when it’s fresh because it loses loft as it settles, and the bubby “champagne” effect is reduced. I say “generally” because there are times when powder can improve over time. We’re in one of those weather regimes now, and every time I head out, the areas of untouched snow just seem to ski better and better. The humidity is low, and each night we’re dropping into the single digits above or below zero F; it’s a recipe for great powder preservation. I already noted the improvement in the snow between my ski sessions on Monday and Tuesday, and here we are on Thursday and the powder just continues to impress.
I had some time to get out for a tour this afternoon, and I managed to catch some sunset skiing on Timberline. Since I’d had such good snow on Tuesday, I actually followed that same route today and stuck to Spell Binder. The top layer of the powder is just feathers, and it gradually gets denser the deeper you go into the snowpack, which is just the way you want if for skiing. I hadn’t been sure if the skiing could be any more effortless than what I’d experience on Tuesday, but perhaps it was today.

Touring skier traffic hasn’t been too busy at Timberline in the past few days, but as always, another storm would be welcomed. It’s certainly not that the quality of the powder needs a reset, but we could use a reset of the ski tracks on the trails. Untracked lines are still there, but they won’t hold out forever, and eventually new snow will be needed.
Erica on Sprig O’ Pine as we enjoy some of Bolton’s great Christmas Eve ski conditions thanks to 8 inches of snow from our most recent Alberta Clipper system
As of their early morning snow report, Bolton Valley had received 8 inches of accumulation from the clipper that began affecting the area yesterday evening, so I headed up for some morning turns with my wife and our younger son. We’re not fully into the holiday week yet, so visitation at the resort was still fairly modest – around the time of the opening of the early lifts, folks were parking in the second and third tiers of the main Village parking areas.
I’d say we found about 8 inches of new snow at most elevations, so that’s right on track with the snow report. The powder was dry, midweight snow – my snow analyses for the storm up to that point came in at 7 to 8 % H2O. Total liquid equivalent from the system stands at 0.42 inches at our site in the valley, so that’s very much in line with the forecasts, and the mountain was probably somewhere in the range of a ½ inch of liquid equivalent. While not enough for a massive resurfacing, it did a decent job of resetting the surfaces atop subsurfaces that are already of decent quality from the past couple of systems.
After a couple days of below average temperatures, we’ve warmed back up into the 20s F now, and with light snow falling and no wind, the weather was fantastic out on the slopes today. We started off with a run on the Vista Quad, and Alta Vista had nice powder and chowder available – it was enough to be bottomless in untouched areas on moderate slope angles. Our timing was perfect for catching the opening of the Wilderness Lift, so we did a couple runs there, then finished off with more runs off Vista and Snowflake. The resort even hit Spillway hard with snowmaking and it’s good to go – my wife and I didn’t ski it, but my son and his friend did and said it was fine for manmade snow.
Conditions on the slopes are certainly good, but the natural snow trails could still use more cover, and the resort will need that to expand terrain into areas where they aren’t making snow. They haven’t yet opened Timberline, most of the Snowflake area, or the Cobrass area, so there’s a lot of terrain still to be made available.
Powder lingers in the trees as cold conditions have preserved the snows from recent storms in the Northern Greens.
The turns yesterday at Timberline were quite good, so I headed back up to Bolton Valley again today for more ski touring. Compared to yesterday, temperatures were about 10 degrees warmer today when I arrived at the Timberline Base. Even though it was cloudy all afternoon ahead of our next incoming storm, the warmer temperatures were quite apparent.
Yesterday I toured in the Twice as Nice and Showtime areas, so today I decided to mix things up a bit and spent most of the tour on Spell Binder. With our sub-zero F temperatures overnight, the snow was extremely well preserved, so the depth and quality of the powder was essentially the same as what I encountered on yesterday’s tour. There may have been a subtle bit of settling in the powder overnight, but I’d actually say today’s turns were better and even more consistent than yesterday’s. It’s hard to say if it was just better overall snow deposition and protection in the Spell Binder area, or the pitch was just right for the conditions, or the snow just settled a bit and set up an even better density gradient in the powder. Perhaps all those factors contributed to varying degrees, but whatever the case, the powder skiing was excellent out there today – bottomless turns with about 8 to 12 inches of medium weight right-side-up powder that made the skiing nearly effortless on fat boards.

Some of the accumulations from our recent storms near the Timberline base
The forecast for today called for even colder temperatures than yesterday, but more snow from the back side of our recent clipper system continued to fall even into last night as the cold temperatures allowed Lake Champlain to contribute moisture for lake-effect snow into the mountains. Thanks to the moisture boost from the lake, we picked up 5 to 6 inches of snow down at our site in the valley, and as of this morning’s snow report, Bolton Valley had picked up 16 inches of snow in the past 48 hours.
With temperatures hovering in the single digits F, touring was the call for today’s ski outing, and based on what I saw up at the mountain yesterday, Bolton’s Timberline area looked ready for exploration. It was 2 F when I pulled into the Timberline base area in the middle of the afternoon, but thankfully there was no wind, and the afternoon sun really helped reduce the chill. There were a few other groups out touring as well, but overall, it looked like a fairly quite Sunday afternoon at Timberline.
The Timberline Uphill Route is in excellent shape, and perhaps because of the temperatures, skier traffic on the Timberline terrain has been quite light. The powder depth at 1,500’ at the Timberline Base is about 6 to 8 inches, and up in the 2,000-2,500’ elevation range it’s 8 to 12 inches. There’s not really much base below the powder down at the 1,500’ elevation, and it’s probably a couple hundred vertical feet up before you start getting a decent amount of base snow. Thankfully, the base elevations down near the Timberline Base Lodge are manageable with the available snowpack because most of the on-piste terrain there isn’t too steep. Above that elevation, the base is sufficient for great skiing aside from scoured areas, steep areas, or areas with underlying obstacles in the snow. The Timberline terrain can certainly support touring traffic right now, but there’s no way it would support lift-served levels of skiing, so we’ll need more snow or the resort will need to put some manmade snow down if they want to start up Timberline lift service in the short term.
As the lake-effect snow continued last night, the flakes transitioned from more dendritic to rather small and grainy, so snow ratios came down to the 8 to 10% H2O range for my last couple of snow analyses from the event. Consistent with those observations, what I found out there today was fairly medium-weight powder. It did a better job of covering the subsurfaces than super light powder would have, and it was still dry enough that bogging down wasn’t any issue even on shallower pitches. I was on 115 mm fat skis, which helped of course, but I don’t think most folks would find movement an issue with whatever skis they had.
Making great use of the cold temperatures: Snowmaking taking place at the 4×4 Center by the Timberline Base
A clipper system is forecast to start affecting the area tomorrow, and Winter Weather Advisories are already up for the western slopes of the Northern Greens. It’s not a huge system, but snow forecasts for the local mountains are in the 6 to 8-inch range and liquid equivalent is up around a half inch in some of the modeling, so it would be a nice boost to the snowpack and snow surfaces if it plays out like that.
A view from near the Bolton Valley Snowflake Lift summit station amidst today’s snowfall
It was a cold one out there today; indeed, it was really a good day to just enjoy lots of indoor activities. But we did just have another storm push through the region, and the conditions on the slopes are good and keep getting better, so I still wanted to get out to see what the new snow was like and get some exercise.
Bolton’s Wilderness Chair was set to open at 10:00 A.M. again, and with the cold temperatures I definitely wanted to warm up with some touring. So, I decided to go with a session like the one on Thursday, which I kicked off with some touring before moving to lift-served turns. When I arrived midmorning in the Bolton Valley Village, it was 7 F according to the car thermometer, and single digits F is definitely midwinter cold. There wasn’t much for wind in the parking area at that moment, so I was encouraged by that while gearing up.
Catching sight of an old Snow Hole trail sign covered with snow along the Wilderness Uphill Route during today’s ski tour ascent
Ascending via the Wilderness Uphill Route was quite comfortable, since it’s well out of any wind, and I was generating plenty of heat. I stopped my tour at 2,500’, enjoyed a run through the powder along the edges of Lower Turnpike, and then hopped on the Wilderness Chair for a ride. My body was warmed up for the touring and Telemark turns, and the wind was happily at my back while I was on the lift, but I could tell it was pretty brutal up there at the Wilderness Summit above 3,000’. The calm conditions from below were gone, and the biting winds along the ridgelines made their presence known. After that trip, I didn’t have much interest in heading up to check out the Vista Summit, so I just stayed low and enjoyed a run off the Snowflake Chair. The warm-up touring definitely helped me stay comfortably warm for a couple of lift rides at least before I headed home.
Powder depths have obviously been bolstered by this most recent system, and conditions are good, but certainly nothing stratospheric for the Northern Greens. One factor in that assessment is that this latest storm was nice, but the snow was quite dry, and it was less of a resurfacing than the previous storm. We picked up about 0.20” of liquid equivalent from this system compared to 0.40” of liquid equivalent from the previous one, so scale those up a bit according for Bolton’s elevation and it gives you a sense for their contributions to resurfacing. The resort is opening more terrain all the time, but lift-served natural snow terrain could still use another solid resurfacing storm with an inch or two of liquid equivalent to take care of the tougher areas. Overall, the natural snow terrain that’s open is quite skiable with good coverage and quality surfaces, and there’s a decent, consolidated base above 2,000’, but you still need to pick and choose your lines somewhat in those spots exposed to wind that get scoured.
The resort was indicating 3-6” of new snow in their early morning report, and I can’t separate out accumulations from this storm specifically, but the changes in surface snow depths between Thursday and today give a sense of the contributions from this most recent event at various elevations. Thursday’s surface snow depths are on the left, and the approximate depths I observed today are on the right in bold:
So, there’s a lot of nice, fairly deep powder above 2,000’, and it’s right-side-up and skiing great thanks to this latest storm’s snow being dry. My observations from down at the house have been giving me snow densities in the 2 to 6% H2O range throughout this latest storm, so indeed it’s some quality powder. The back side of this system has actually been aided by some direct lake-effect off Lake Champlain. The bands were mostly oriented to affect the Champlain Valley earlier in the morning, but as midday approached, the bands shifted such that they were more directly hitting the mountains. That definitely helped keep it extra snowy throughout the day and boost accumulations.
Enjoying some of the snowy trees in the Wilderness glades on my ski tour this morning at Bolton Valley
Tomorrow is supposed to be even a bit colder than today, so if I head out it will just be for a tour vs. riding any lifts. After the warming and consolidation earlier this week, it looks like Timberline is probably getting in shape to support some good touring and powder skiing again, so I may stay low and tour there if a ski session comes together. We’ll see how much additional snow the resort is reporting in the morning, but since we were getting hit at our place by those lake effect bands right into the evening today, Bolton should have been getting even more of that snow. The models suggest we’ve got another couple of clippers affecting the area over the next few days, with warmer temperatures as well, so that’s looking nice moving into the holiday week.
The number of visitors at the resort seemed a bit less today – there was no sign posted about the Village lots being full, and we easily grabbed a parking spot in the upper lot by the entry to the Backcountry Network. With cold temperatures preserving the snow, conditions were similar to yesterday with 1 to 2 feet of powder available wherever wind hadn’t scoured it to lower depths. Touring some of the higher elevation trails allowed us to see the various areas that had been hit by wind, and you just had to be cognizant of where winds had affected the snowpack to pick the lines with the best undisturbed powder. The middle elevations were much less disturbed by the wind, and you could pick just about line and get some great powder turns.
