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:
340’: 0.5-1”
500’: 1-2”
1,000’: 3-4”
1,200’: 3-4”
1,500’: 4-5”
2,000’: 8-9”
2,500’: 9-10”
3,000’: 9-10”
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.
