I had time to head up to Bolton Valley for another ski tour this morning, and the weather was very much like what we’d had in the mountains for the past few days: temperatures in the single digits F with a lot of wind. Thankfully, yesterday appeared to be the coldest of the days this week, and the temperatures this morning were about 5 to 10 degrees F warmer.
Yesterday I’d done a bit of lift-served skiing after my tour, but today I decided to make my tour a bit longer instead of sitting on the lifts. On my ascent I topped out around 2,900’ on Wilderness, and I figured I’d gone high enough to get a good sampling of the snow at various elevations.
With a few more inches of snow each day, the conditions on the slopes have just continued to improve aside from those areas exposed to the wind where scouring has been incessant. Exposed areas just continued to be scoured, and I wouldn’t be surprised if some of those exposed spots had less snow than they did before this system began. Protected areas had simply fantastic snow though. Like yesterday, I typically measured 20 inches or more of powder in protected areas today, and the subsurface snow is a distant memory there. I also measured depths as great as 35 inches in some non-drifted spots, where it seemed like I was just pushing down into the older layers in the snowpack without even hitting any firm layer to differentiate the snows from these recent couple of systems. That’s a good sign about the overall quality of the snowpack though if you can’t even find a subsurface layer until you head down 35 inches into the snow.
With the end of this most recent long-duration system, it looks like we could be moving into a pattern featuring some Clipper systems. The first one is coming into the area tomorrow, with another expected for Monday into Tuesday.
I’d hoped to head up to the mountain for some turns yesterday afternoon to see how accumulations were settling in from our current system, but it was a bit close to sunset after I finished the work I wanted to get done. I wasn’t too worried about it though, since this is another long-duration system, and the snow accumulations are slowly building up. I did manage to get out for some turns this morning on my way into Burlington, so I can report on that outing. In the weekly forecast, today had the coldest temperatures of any day, with valleys in the single digits F. So, in that respect, this wasn’t my preference for days to get on the skis, but it’s been snowing, and it worked out.
In most respects, the weather up at the mountain was sort of status quo for what we’ve had over the past several days – at the Village elevations it was still in the single digits F. In this case, the temperature was barely in the positive category, but it can definitely get far worse in January. A big current factor in comfort on the slopes though is the wind – those winds are still howling out there with this system. With that in mind, I started the morning with an ascent via the Wilderness Uphill Route to get my body up to temperature, and that worked well. Then I was warm enough to take a trip up the Vista Quad and make another run.
The snow report from Bolton Valley was indicating 6 inches for their 48-hour total/storm total as of this morning, which doesn’t seem like much, but this system has brough decent moisture with it. The flakes have been small in many areas because of poor dendritic growth. Combine that with those winds blowing it around and packing it together, and measuring accumulations in the mountains has been tough. For example, I’ve recorded almost a foot of snow from this system down at my house in the valley, not because we actually got more liquid equivalent than the higher elevations, but because we’re sheltered from the high winds, and the dendrites can actually stack up with loft and not get smashed and compacted. In any event, we’ve recorded about a half inch of liquid equivalent from this storm so far at the house, so the mountains have probably picked up somewhere between a half inch and an inch of liquid. In areas protected from the wind, such as by the Miso Toh Kome hut, there are some snow stacks that give you a nice sense of how much has fallen with this event in unscoured areas, and the stacks looked like they were about 10 inches deep.
In terms of the ski conditions, with a lot of its terrain facing west, those usual exposed areas at Bolton without snowmaking are scoured down to just a couple of crusty inches. Areas out of the wind have lots of great medium-weight powder though. Measurements I took in protected, non-drifted areas in the 2,000’ to 2,500’ elevation range revealed up to 20 inches of powder, so where it’s not blown away, even the lower elevations of the main mountain are really starting to accumulate quite a stack of surface snow atop the base. I skied Lower Turnpike on my touring run at Wilderness, and being protected from the wind, it had great snow wall-to-wall, with some spots having a foot of powder, and others just a few inches of powder if they had seen grooming and/or skier traffic. With the cold temperatures, the snow was a bit slow, but not so slow that I had trouble maintain speed even in those deeper areas of powder. Off the top of Vista, I stayed away from Spillway and Hard Luck, which are much more exposed and get scoured, and chose Vermont 200, which is much more protected. It had just a couple of small, scoured spots, but beyond that it was a playground of 1 to 3 feet of nearly untouched powder depending on whether or not you were blasting through a drift.
Although we’re not currently getting tons of champagne powder turns from this system with its prodigious winds, I did notice one great thing that this current system is doing. Aside from some nice resurfacing outside of the exposed areas, the winds are really filling in any of those deeper water bars in the lower elevations that just hadn’t managed to get there yet. I really noticed it on Lower Turnpike – there are those certain water bars in lower elevations where you have had to direct yourself to an optimal spot along the width of the trail because it’s got the smoothest transition for crossing. That issue has largely disappeared now with this meaty snow being driven into the hollows of the water bars by those winds.
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.
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.
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.
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.
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.
I told E about how good the skiing was yesterday, so she was interested in getting out and the two of us headed up to Bolton Valley today for another tour. Thanks to the ongoing lake-effect snow from Lake Ontario, surfaces have been getting some nice freshening. Since my report detailing the snow conditions during yesterday’s tour, we’ve had another inch or two of additional snow down at the house in the valley, so I’m sure Bolton has had at least that much as well. It was really dumping when I left yesterday afternoon, so that period alone should have contributed some nice accumulations.
Between settling and the additional snow that’s been falling, snow depths seemed to be just about where they were yesterday, so just refer to the detailed snow depth profile I provided in that post for approximate snow depths that were out there today. Temperatures were in the mid-20s F out on the mountain early this afternoon, so it was just a bit cooler than yesterday, and consistent with that, the snow was a bit drier. Whereas yesterday I estimated the upper layers of powder in the snowpack to be in the 8% H2O range, today I’d say we were hitting powder that was more in the 6 to 8% H2O range. E is notorious for getting out on the snow one day too late when conditions aren’t as good as the day before, but that wasn’t the case this time. While there were a few more tracks out there today than what I found yesterday, the dry air and drier snow falling kicked the quality of the powder up a notch. The existing base snow, the continued settling of the lower layers of surface snow, and new rounds of dry snow coming in have set up some beautiful right-side-up powder. The drier nature of the powder was evident in the way it was even easier to ski lower-angle slopes; I’d brought fat skis to help in that regard, but my wife was on mid-fats, and she had no issues maintaining speed on even the mellowest pitches. So once again, essentially any mowed terrain from roughly single black diamond pitch down to gentle slopes was in play for great powder turns today.
In terms of the ongoing snowfall, today was much like yesterday with continued light snowfall of varying intensity throughout our tour, and it was steadier when we were finishing up our descent, but not nearly as heavy as when I was leaving yesterday. The direction of the more intense incoming moisture from Lake Ontario seemed to be a bit more to our north today, but it sounds like the Jay Peak area has been doing well from that setup.
The first flakes of the season at our site in Waterbury were back on the 16th of the month with that last big snow event, but thanks to the system moving through yesterday into today, we accrued the first accumulations I’ve seen here. Temperatures were certainly above freezing here in the valley, but the intensity of the precipitation is what brought on the accumulation when one of the more active cells on the radar came through our area.
Based on posts that were showing up in the Northern New England thread at the American Weather Forum yesterday, it was clear that many valley locations were starting to see accumulations as the temperatures came down. Temperatures dropped well into the 20s F overnight, so by morning, CoCoRaHS reports revealed valley accumulations of anything from a trace to as much as a few inches in a stripe across Northern Vermont.
With this latest round of autumn snow culminating in over a foot of accumulation on Mt. Mansfield, the setup was calling for some early season turns. With the way the temperatures were expected to rise today, I think yesterday was the way to go for potentially the best overall snow quality for powder turns, but I was too busy to get out to the slopes. I did get out this morning though, and while snow preservation was undoubtedly better yesterday, the clouds totally disappeared today to reveal incredible snowliage in the sunshine.
I started my ascent from the Gondola base at 1,600’ and walked with my skis on my pack for a few minutes to get above the areas with the most melting, then I transitioned for touring and skinned up from there. The snow was already becoming spring-like down low in the sun, and areas in the shade featured refrozen snow. So even yesterday, the freezing level made it above the base elevations. I encountered my first real winter snow that had not seen a thaw-freeze cycle at about 2,800’ in the shade, and then at around 3,200’ I began finding some winter snow even in the sun. I made snow depth checks along the way, and here’s the depth profile I found in the late-morning to midday period:
Depths had consolidated a bit even up at 3,600’ based on Powderfreak’s pictures from yesterday, and the sun was really doing a number on the snow down low. The Gondola terrain gets hit by the sun, and the accumulations down near the Gondola base were just about gone by the time I finished my descent.
In terms of the skiing, I encountered just about every sort of condition that Mother Nature can throw at you, from dense, silky powder, to refrozen areas with unbreakable melt crust, to spring snow, to sticky, freshly melted snow. Once you were down below the driest snow up top, the best approach was to fucus on the snow that was in that happy medium between seeing the most sun on the skier’s left, and that which had seen no sun on the far skiers right in the shade of the trees. The snow on the skier’s left that had seen some hours of sun was getting sticky, and snow that was shaded by the trees was still frozen with either an unbreakable or breakable melt crust, but in between there was an area of quality snow that had seen just enough sun to soften up but not get sticky. Once you were down below roughly 2,000’, everything was melting, so you just sort of kept going until you felt the snow was too thin. You could still make it all the way to the base with the help of shaded areas depending on what level of rock skis you might be on, but I took off my skis for the last few hundred vertical because I didn’t want to beat them up too much.
That was a solid dump for the middle of October though, and with the bonus snowliage it was a great way to kick off the season.
This was a great early season event for the local mountains, and even at elevation, there were still enough leaves left on some of the trees to create excellent snowliage images.
We had our first reported snow of the season here in Vermont over a month ago when flakes were spotted atop Jay Peak, but this latest round of winter weather has now brought us the first actual accumulations of the season. Our initial images of the accumulations came out yesterday morning when Powderfreak sent out some shots from the higher elevations of Mt. Mansfield during his usual Stowe Mountain Resort duties. Later in the day he sent along a nice image of the cloud ceiling and flakes falling on Spruce Peak while he was out on an afternoon hike. The snow was down to at least the 3,100’ elevation as of the afternoon, and with more moisture pushing into the spine of the Greens according to the radar, the potential for some additional overnight accumulations was looking good. The moisture seemed to be drifting a bit south though, and I saw a comment from Powderfreak that he felt the Central and Southern Greens would have the better chances for accumulations during the overnight period.
