I hadn’t been up to the mountain since Saturday, so I was eager to get out for a ski tour when I had time today. There’s been no specific synoptic storms in the area, but the snow has been piling up the thanks to the continuous feed of moisture off the Great Lakes and the upper-level low pressure to our north. Seeing the snowpack depth at the Mt. Mansfield stake quickly jump up to near 20 inches is a strong sign that it’s been snowing around here. Having that closed upper low over Hudson Bay with broad upper level troughing is a great setup when you have a 4,000’ wall of mountains sitting downwind of a moisture source like the Great Lakes.
Even without data from the Mt. Mansfield stake to go on, I know it’s been snowing because we’ve recently had several inches of new snow down at our place in the valley, so the snow is hitting all elevations with the current temperature regime. Indeed, I found that snow depths were up substantially at all elevations during today’s ski tour. I toured again using the Wilderness Uphill Route, so I was able to check snowpack depths from the valley on up and compare them to what I’d last seen on Saturday. The updated snow depths are below, with Saturday’s depths listed first, then today’s depths following in bold. The depths I found up at 3,000’ and above are certainly consistent with what is being reported for the snowpack depths at the Mt. Mansfield stake.
Concomitant with the increasing depths, the quality of the powder skiing even jumped another notch relative to the already great conditions we experienced on Saturday. In fact, even though the surface snowpack is excellent right-side-up powder that is beautifully dry, it’s getting deep enough that it’s starting to be a bit too much for the lowest angle slopes if you’re in fully untracked snow. I’d brought my 115 mm fat skis for today’s tour because they had already been a good choice on Saturday, but I was glad to have them for planing more efficiently on the lowest angle slopes today.
Indeed, it was snowing today during my tour akin to what’s been happening for the past several days, but today’s snowfall was lighter and less consistent than what I experience on Friday or Saturday. Our next Clipper system is now coming into the area though, so snowfall should pick up with that. We’re under a Winter Weather Advisory here along the spine of the Northern Greens, and the latest BTV NWS Event Total Snowfall map currently has some areas of 8-12” and 12-18” shading.
As of their 4:00 P.M. update, Bolton was reporting a foot of new snow so far from this current winter storm, and I’m sure they’ve cruised right past that mark with the way it was snowing up there when I left the mountain this afternoon.
The early morning report from Bolton was 6 inches new up top, so my wife and I planned to let a few more inches accumulate and then head up in the afternoon for some lift-served runs. That plan quickly changed around 11:30 A.M. when we noticed that their main base area live webcam was frozen. We checked their website and they’d updated the snow report to indicate that they’d lost power. They were working directly with Green Mountain Power and hoped to get it back up in an hour, but that was very much up in the air.
About an hour later with no change in operating status at the resort, I figured it was time to head up for some ski touring to get out in the new snow, since the potential for lift-served skiing was just too uncertain. When I first arrived up at the mountain, the snowfall was steady but I’d say only moderate in intensity. I did some quick depth checks around the Village to get a sense for how much new snow was there, but it was tough to gauge. In many areas, the new snow was so well blended with the old snow that it was hard to determine where the interface was. Overall, that’s a great sign because it indicates that the snowpack wasn’t hit too hard by the warmer temperatures on the front end of this system. In some spots I could find a thicker layer below the new snow, but even at that point I was often getting surface snow depths of 12 to 14 inches. Whatever the accumulations, there’s plenty of new snow and it’s coming together nicely with the underlying snowpack.
I skinned up to the Wilderness Summit, and touring traffic at that point seemed very light – there were just a couple of tracks down Peggy Dow’s. As I ascended, the intensity of the snowfall increased, and when I was up above 3,000’ on Wilderness it was definitely in the 1-2”/hr. range at times. I know it’s really dumping by how quickly my gear takes on snow accumulations during touring transitions, and this was one of those times where I was constantly having to brush off the snow.
Fat skis were the call again today, and this snow is on the denser side, so you want some pitch for the best turns. In terms of density, at 2,000’ the snow seemed to be a bit above the 10% H2O range, and up at 3,000’ it’s definitely drier; it’s got the feel of something in the 7 to 8% H2O range. The turns are great anywhere at elevation of course; it’s simply bottomless powder everywhere with this storm putting down plenty of liquid equivalent. I was worried about some of the water bars getting blown out with the warmer front end of this storm, but in general they seemed similar to how they were before. The snowfall didn’t actually slow down when I descended back to the Village, so it wasn’t just 3,000’+ that was getting hammered at that point – the intensity of the snowfall had definitely increased in association with the back side of the storm.
The mountain had been running at least the Snowflake Chair when I started out on my tour, so my plan was to swap over to mid-fats and get in a few lift-served laps to finish off the session. Well, when I arrived back at the main base, power was out again everywhere, so that plan was out the window. There was an easy solution to that though; I just slapped the skins back on and kept touring. I was initially thinking a nice little tour up to the Snowflake Summit would be a great way to finish off the session, but when I got to Five Corners I suddenly thought about hitting the Timberline Summit. I haven’t been up to Timberline at all yet this season because the snow depths at the Timberline Base are still a bit lean compared to the stronger snowpack above 2,000’, but that part of the tour gave me a chance to check out Timberline’s higher elevations. There’s been hardly any skier traffic over there, so it’s nearly untracked everywhere.
Heavy snowfall continued to pummel the area right through to the end of my ski tour, and my car had been loaded with snow in just the couple hours that I was out there. It took me probably 10 minutes to clean off the snow. The temperatures had definitely dropped as I was heading down the access road, and the heavy snowfall didn’t start to abate at all until I was below 1,500’. We’ve been accumulating better even down in the valley now that the temperatures have dropped below freezing.
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.
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:
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.
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.
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.
