With the Thanksgiving winter storm wrapping up overnight, today was clearly a day to get out for some skiing, but I wasn’t initially sure where I was going to go. The storm seemed to be more potent further south based on observations that I’d seen, as well as images from mountain cameras like the Okemo snow stake webcam and the Sugarbush snow stake webcam – they both showed about a foot of new snow at elevation. We’d been watching Bolton Valley’s webcams throughout the storm, and the resort was certainly getting some decent accumulations, but Bolton doesn’t have a specific snow stake webcam and it was a bit difficult to get a feel for just how much they’d received from the wider views. This morning, I perused a variety of mountain webcams from around the state, and in the end, there didn’t seem to be all that much difference in practical base area accumulations and coverage between what I was seeing at Bolton and the various resorts father south. I also checked on how much liquid equivalent was in the new snow, since that has such a big impact the quality of the skiing, and while the Vermont CoCoRaHS numbers seemed to be around an inch of liquid to our south, we’d picked up over 0.6 inches of liquid in the snow that fell at our house in the Winooski Valley, so I’d expect Bolton Valley to have picked up at least that much. With some base snow already in place at Bolton, that felt like plenty of snow for some good touring and turns.
Overall, the decision ended up being relatively easy, and I headed up to Bolton around midday. Down at the base of the Bolton Valley Access Road at 340’, new snow accumulations were just spotty, with areas of grass visible, but by the time I hit the Village at 2,000’, I found 6 to 8 inches of fresh snow, so the skiing prospects were looking good. I ascended by the Wilderness Uphill Route, and the skin track was nicely set. I probed snow depths throughout the tour, and by the time I hit the Wilderness Summit at roughly 3,150’, depths were in the 12 to 14-inch range. Above 2,000’ there was already existing snowpack in place, so the higher-elevation snow depths I measured on today’s tour weren’t necessarily all from this most recent storm, but here’s the detailed snow depth profile from today:
340’: T-1:
500’: 1”
1,000’: 2”
1,200’: 2-3”
1,500’: 3”
2,000’: 6-8”
2,250’: 8-10”
2,500’: 10-12”
2,750’: 11-13”
3,000’: 12-14”
Although the precipitation from this storm was 100% snow even at our site at 500’ in the valley, temperatures were around freezing down low, so the accumulations were quite dense. That wasn’t the case up on the mountain though – the snow was considerable drier, and the powder was of good quality. It was clearly sub-10% H2O powder, and if I had to guess it was probably in the 8% H2O range above 2,000’. I’d brough mid-fat skis today since I was initially unsure of how deep the powder was going to be and how good the overall coverage would be, but one could easily go with fatter skis if they wanted. With some existing dense base snow in place, even black diamond terrain was easily in play today. You’ll still want to be on mowed, on-trail terrain though – I suspect that venturing onto anything with too many obstacles would find you hitting things below the base. And the trees are still not ready yet – the base isn’t deep enough to cover the typical obstacles in the woods. Today’s powder turns were great though, and the snow was dry enough that even low-angle terrain was fun. Fat skis could help there for a bit more planing and speed if you’re on the fence about what width to shoot for.
Thanks to our upwind friend Lake Ontario, snow was falling the entire time I was out touring. For most of the tour the snowfall was of varying light intensity depending on whether a larger pulse of lake moisture was hitting the spine or not, but it jumped up to borderline heavy snowfall when I was leaving a bit before 2:00 P.M. There was a good shot of moisture hitting the mountain at that point and the top half of the Bolton Valley Access Road had taken on enough accumulation that people were really taking their time on the descent. With the lake effect snow event taking place right now, we’ve had about another inch of new snow down here in the valley, so I suspect they’ve had at least another couple of inches up at the resort. And there’s more moisture pushing into the area this evening based on the radar, so there should be some additional freshening of the powder surfaces for tomorrow.
