One approximate measure of when the potential natural snow/off piste skiing begins each season here in Northern Vermont is the date when the snowpack at the Mt. Mansfield Stake reaches 24 inches. This is by no means an exact date, especially since it’s possible to get great turns on just a few inches of snow if the snow is dense and the underlying surface is grass instead of rocks. You can indeed get by with much less than 24 inches of snowpack if the snow is very dense, but not if it’s all Champlain Powder™ fluff. Based on empirical observations and reports from skiers in the area each season though, hitting the 24” mark is reasonable for most situations.
With that preface, let’s take a look at where last season sits with regard the start of the natural snow/off piste skiing around here. By most accounts, last season started off with bang. Even in the local mountain valleys, the winter snowpack started as early as November 10th. That’s very early for the valleys, and when the valleys are doing well, the mountains certainly are too.
The updated plot for the 60+ seasons in the Mt. Mansfield Stake database is below, with last season represented by the red star:
Before I add a bit of context to last season’s start, here are the stats for the data set:
Mean: Dec 12th
Median: Dec 9th
Mode: Dec 16th
S.D.: 18.8 days
Entry of this year’s data point had no effect on the mean, mode, or S.D. (within a tenth of a day), but it did drop the median by one day from Dec 10th to Dec 9th.
The plot would suggest a reasonably good start, but nothing outrageous: last year’s 24” date was Nov 27th, which is only 0.78 S.D. ahead of the mean, so well within 1 S.D. That puts it in roughly the top 22% of seasons, so about 1 in 5 seasons will have a similar or earlier 24” date.
While the 24” date is a nice snapshot for the start of the natural/off piste season, there are of course a number of other factors to take into account that made last November more impressive than that number alone:
1) Near miss: If you look at the raw November stake depth data (posted below), you can see that the snow depth at the stake reached 23” on Nov 21st. That’s as close of a miss as you can get to hitting 24”, so even as of the 21st of the month, the snowpack had essentially hit that two-foot level. Getting to that level by the 21st brings a season past 1 S.D. and into that top ~15% of seasons. That’s not a huge bump in this regard, but having nearly an extra week of borderline two-foot snowpack at that part of the season could easily mean an entire additional weekend of natural snow skiing potential.
2) No going back: This is a much bigger feather in last season’s cap. Even from about mid-month, the snowpack never really took a major hit, and once it did hit that 24” mark on Nov 27th, there was really no going back. It sailed past 24” and just kept climbing as you can see in the numbers at the end of the month. I haven’t added the December numbers below, but even with the lackluster December we had, the snowpack never dropped below ~40”. That can’t be said for all of the seasons on the left side of the plot (certainly not Mr. October out there in front, which was the 2006-2007 season – he was back to 0” at the stake by mid-November).
3) Snow-depth days: I haven’t calculated this for any November with the stake data, but it will obviously be a good integrative measure of how much snow was on the ground for the start of the season. I’m sure last November would have a solid ranking if I put those data together.
So, if we look into that left side of the plot, do we have any other recent seasons in there that we can use for comparison to last season?
Actually, that lone star (Nov 25th) just to the left of the red star for last season is for 2007-2008. We know that was a solid season around here. The snowpack began building in the first week of November, and there was really no going back there either. Unlike this past season, that solid November was followed up by a stellar December (almost 70” of snow here at the house) and the Mansfield snowpack was hitting five feet by the holidays. With a solid December, last season certainly would have given 2007-2008 a run, but instead it was languishing at around 40” at the stake during the holiday period.
With regard to some of the other stars up at that end of the plot:
The two compatriots of last season on the plot, those other two stars on Nov 27th, are 1997-1998 and 1977-1978. 1997-1998 looks pretty solid with a snowpack start in the first week of November, and snowpack at about that five-foot mark by the holiday period. There’s also a nice-looking bonus stretch of snow at the end of October, with snow at the stake for almost the last third of the month, and the depth peaking at 16”. Checking my archives, I actually went for some lift-served skiing at Sugarbush on Oct 28th, so that speaks to that period snow being a bit of something special. 1977-1978 was before my time around here, but it looks a bit tamer. There was nothing in October, then snowpack began to build around mid-November and was getting around the four-foot mark by the holidays.
The two stars right at Nov 20th are interestingly, back-to-back seasons of 1967-1968 and 1968-1969. Both had a little October snow, and then a snowpack start in the first week of November. Both had pretty steady climbs right through November and December, with 1967-1968 getting to around 40” for the holiday period, and 1968-1969 hitting a very robust 6+ feet of snowpack for the holidays. I guess that shouldn’t be too surprising, as that was just the start of a season that would become legend.
The star at Nov 18th is 1965-1966, and the progression looks sort of like 1967-1968. That’s quite a 4-year stretch of good early seasons from ’65-’66 to ’68-’69 with those three solid starts.
The star at Nov 16th is 1980-1981. That season is interesting in that the snowpack started building on Oct 20th and sailed right into November without ever going back to zero. Snowpack was 4+ feet for the holidays, but the rest of the season looks modest (relatively speaking) with the snowpack depth never getting above 6 feet.
The star on Nov 14th is for something more recent: 2003-2004. I was out in Montana for that one, but snowpack started building in the second week of November, it was 4+ feet at the holidays, and hit the 100” mark in March.
The star on Nov 13th is for 1976-1977. That looks like an impressive start, with snowpack taking hold in the second half of October, climbing right through November, and hitting roughly the 4-foot mark for the holidays. The stake didn’t quite top out at 100” that season, but it did pretty well topping out at 94”.
The final early star I haven’t mentioned yet is the one on Nov 11th, that’s for the 1990-1991 season. It seems like the only other boom and bust start to go with Mr. October (2006-2007). There was a little inkling of snow at the end of October and start of November, but snowpack started building at the end of the first week of the month and topped out at a very impressive 45” on Nov 14th! It was a downhill slide after that though. The snowpack never went lower than 9” but there were only 12-18” on the ground for the holiday period, and on Dec 30th it dropped from 18” to 13”, so that must have been quite a dagger in the holiday week (I guess that depends on whether it was a nice spring skiing day or a nasty rainstorm). The rest of that season seemed pretty blasé because the snowpack never even hit 5 feet. I don’t recall much about that season, but I’m assuming there was nothing too remarkable.
We’re pleased to announce the completion of our Bolton Valley Photo Gallery for the 2012-2013 ski season. This year’s gallery is our largest to date, with over 270 images documenting this season’s ski adventures indoors and out, in the front, side, and backcountry, under blue skies and flake-dumping maelstroms at Vermont’sBolton Valley Ski Resort. Continue on to the thumbnail images below and browse away! Detailed reports are associated with every photograph in the gallery, so if you find a scene that sparks your interest, simply hover over the thumbnail image to get the date, and head to the archives on the right side of the page to read the full report. We’ve also got similarly extensive galleries from the past several ski seasons, representing nearly 1,600 photographs from around Bolton Valley, and these can all be found at our J&E Productions Photo Galleries Page. We’ll also have our full 2012-2013 Ski Season Summary coming out later this summer, so stay tuned for that update as well.
With everyone having their own unique perspective on skiing, some of which you can discover at supreme ski morzine skiing school. They tend to love skiing since they teach people how to do it! But combined with the multitude of weather-related factors involved in winter recreation in general, there’s usually ample room for debate about where a ski season sits relative to average. However, when it comes to the 2011-2012 ski season in Northern Vermont (and perhaps to an even greater extent in other parts of the Northeastern U.S.) most any metric would set it firmly in the lower half of seasons. Some key contributing factors to the outcome of the season were temperatures, which were above average for every month from October through May (specific monthly temperature departures are available in the monthly detail section), overall precipitation, which was well below average during that period, and as expected with that combination, snowfall that was well below average. However, the numbers don’t always tell the whole story, and indeed that was the case in Northern Vermont this past season. If numbers aren’t everything, perhaps timing is everything, and the snow machine of the Northern Greens exhibited some impeccable timing for some of the busiest ski periods when it came down to it. There was also a consistency and intensity in backside snows that seemed to heal just about every mixed precipitation event. So while I don’t think that the winter of 2011-2012 can be considered anything but below average around here, the bigger story might just be how “surprisingly good” it was. That story unfolds in the details below.
Tree Skiing:In the past I’ve used empirical data from trip reports to establish a mean date for the start of tree skiing in Northern/North-Central Vermont, and as I outlined in last year’s ski season summary, that analysis revealed a date of December 10th ± 13 days, with an average depth at the stake of 28.1 ± 6.5 inches. However, after a comment from Powderfreak back on December 12th, in which he indicated that he’d observed tree skiing on appropriate terrain at Stowe to start roughly when the snow depth at the Mt. Mansfield Stake hit 24 inches, I decided to run an analysis using snowpack data from the stake. Instead of just the 15 to 20 seasons worth of ski trip reports that are available since the arrival of the internet era, there are almost 60 seasons worth of data available from the Mt. Mansfield Stake. Analysis of the stake data using the first date of attaining 24″ of snow depth or higher as the start of tree skiing, actually produced a very similar result (December 12th ± 19 days, with an average depth at the stake of 25.8 ± 2.7 inches) to what was obtained from the empirical data. With the date being so close to what I determined from the empirical data, I’m pretty confident that the date of attaining 24″ in the stake data will serve just as well in determining the average start of tree skiing, and the relative start date for individual seasons. With the median and mode for that analysis coming in quite close to the mean, the distribution seems normal, so the standard deviation in the data should have some predictive value. This “24-inch rule” isn’t meant to replace the traditional “40-inch rule“, but it’s there to compliment it as a more practical measure of when people actually start venturing into the trees in this area (the fact that it is corroborated by many years of empirical data can testify to that). The point at which the stake hits 24 inches is a decent mark for when appropriately maintained trees are going to start offering up good turns for those with the right skills and knowledge, whereas once the stake hits 40 inches, skiers can pretty much venture into most off-piste areas with a good degree of confidence. Between those two points is going to be a continuum of increasing access to off piste terrain. Moving from the 24″ depth to the 40” depth will typically take place during the month of December, with the snowpack at the Mt. Mansfield Stake reaching the 40″ mark at the beginning of January on average.
So where did the 2011-2012 season stack up in terms of the start of tree skiing in Northern Vermont? Not surprisingly, when assessed by the new method of reaching 24″ at the Mt. Mansfield Stake, it’s down near the bottom of the pack. Below, I’ve added a scatter plot that I generated using the Mt. Mansfield snowpack data; the X-axis is a timeline spanning from October to January, and the blue stars represent the dates when 24 inches of snow depth was attained at the stake for the various years from 1954-2012. The red data point is for the 2011-2012 season (date of attaining 24″ = January 3rd, 2012), so the season is indeed more than one standard deviation on the late side (the large vertical line in the plot is the mean, and the small vertical lines are ± 1 standard deviation), although it actually isn’t as late a start as some seasons:
How did the 24-inch snowpack depth analysis compare to what we actually found on the ground this season? Since skiing natural snow terrain on piste began first, I’ll mention that momentarily before discussing the trees. I saw the first signs of people skiing natural snow trails this season on December 27th at Bolton, and coverage certainly looked sufficient on at least moderate terrain. The tracks I saw at that point already looked old, and I suspect that on piste natural snow coverage was actually sufficient the day before (December 26th), thanks to the Christmas Day storm. Bolton picked up close to a foot of snow from that storm, and at the end of the day on the 26th, the snow depth at the Mt. Mansfield Stake came in at 14″. The first day that we actually ventured into the trees at Bolton Valley was December 29th, and as I stated in my report from that day, we only ventured in for one run because the base was just a little too thin to really ski with confidence in there and enjoy it. And, when the snowpack was measured at the Mt. Mansfield Stake later that afternoon, the depth was 21 inches, just a bit shy of that 24-inch mark. By the next day, we were skiing natural snow trails with more than enough coverage, but it wasn’t until January 7th at Bolton that I commented about some of the trees finally being ready after the boys and I skied Wilderness Woods. The measurement from the stake came in at 24 inches that afternoon, and we were clearly reaching another threshold of sorts, so attaining that 24-inch depth at the stake was indeed a decent measure for the start of tree skiing this season in our experience. Powderfreak and I have discussed how that 24-inch number is going to be quite rough, since a 24-inch depth attained mostly with fluff will represent something substantially different that a 24-inch depth attained with cement, but it looks like it’s going to be a reasonable approximation of when people start to take their initial forays into the trees and find the conditions good enough to stay there.
Looking at tree/off piste skiing for the season as a whole, there’s no question that it was curtailed relative to normal. The very late date of reaching 24 inches at the stake in the beginning of January (January 3rd) is 1.13 standard deviations beyond the mean according to the Mt. Mansfield snowpack analysis, putting it close to the bottom 10% of seasons. When this is coupled with the large amount of melting in Mid March due to record heat, which closed a lot of terrain, it equates to a tree skiing season that is roughly 2 ½ months long, compared to the more typical length of 4 to 5 months. The off piste season was certainly condensed, and while coverage was there to enable plenty of access in January (Stowe reached 100% open status by January 14th), tree skiing really seemed to take forever to hit its stride; to wit, the snowpack at the stake didn’t hit the 40-inch mark until the end of January.
Snow Quality: In last season’s summary, I checked my trip reports and found those days in which we were skiing powder, typically suggesting a fairly high level of snow quality, and those days in which powder skiing wasn’t available, often indicating some sort of thaw (or in one case this season, insufficient base depths). For the list of outings below, I’ve again placed a P whenever we were skiing powder, and put a red X if we weren’t, to reveal the temporal pattern associated with that categorization. Outings with an X may still be providing decent skiing such as wet snow, corn, etc. (or else we’d probably be doing something other than skiing) but aside from the spring period, there’s going to be a price to pay in terms of snow quality after these episodes when temperatures eventually cool back down. Chronologically, the first X appears for the outing on December 10th at Bolton Valley. The lack of powder skiing on that date wasn’t actually due to temperature fluctuations, but instead due to the fact that there just wasn’t enough natural snow; substantial snowfall was very slow in coming in early December. The natural snow depth up above 2,000′ in the Bolton Valley Village was still only 2-3″ at that point, so short of junkboarding, skiing was really restricted to just the limited terrain that had manmade snow. The next X appears on our Bolton Valley outing on December 31st, and it represented a notable bump in the winter weather. The holiday week wasn’t too cold, but it was certainly snowy like one would expect at Christmas time in Vermont, with three decent snowstorms totaling more than two feet of snow at the northern resorts (refer to the December entry in the detailed monthly section for more information). So there was indeed some great powder skiing during that stretch. The main factor that kept the overall quality of the skiing from being really outstanding was the lack of base. The natural snow terrain that was open was excellent, but there still hadn’t been enough snow to open the steepest terrain without snowmaking. The X in this case comes in at the tail end of the holiday period where there was a thaw. I described the skiing on New Year’s Eve as reminding me of the Pacific Northwest, with low hanging clouds on the mountains, and dense snow underfoot. I’m not sure how long the resulted firm snow conditions lasted, because three small to moderate storms came through the area that week, with the first one dropping a half foot of snow in the mountains. By the following Saturday there was powder skiing again for the weekend. From that point on there were no interruptions in powder skiing though to mid March – at least from our perspective; we don’t ski every day of course, but we did ski every weekend through that period. However, Powderfreak does ski just about every day of the season at Stowe, and he noted that there were only a few select days without powder. I’ll speak more about that at the end of this section. By far the section of the outings list that stands out the most is the second half of March – the dramatic change in conditions is quite obvious, with seven outings in a row marked with an X. Record warm weather came in with a vengeance in mid March, and it was all spring skiing until the weather cooled back down to normal levels and produced snowstorms for the final two thirds of April. We finally finished off our season with a couple of corn snow days in May, a point in the season where that type of snow is the norm.
The 2010-2011 ski season was the first one to which I applied this type of powder skiing analysis, and relative to what I thought it would look like, I was certainly surprised by the consistent availability of powder conditions once I saw the data lined up. But as surprised as I was with that result, the 2011-2012 analysis is even more astounding. Somehow there was good to great skiing every weekend/holiday period throughout most of the core ski season, despite the overwhelmingly warm temperatures and low snowfall. As I mentioned above in the snowfall section, Bolton Valley reported just 159″ of snow for their entire season. That’s ridiculously low – it’s half their usual snowfall, and we typically average more snow than that at our house, almost 3,000′ below the upper elevations of the resort where the snowfall measurements are taken. That amount of snow might suffice for some decent skiing in an environment like the high elevations of the Rockies with very consistent winter temperatures, but this season in Vermont was anything but that. There were temperature issues throughout the season, and January was a perfect example – at the end of the month, local meteorologist Roger Hill pointed out that we’d had seven January thaws. I had many ski weather-related conversations with Powderfreak in the 2011-2012 ski thread at American Weather’s New England Subforum about the surprisingly high quality of the skiing, and there was certainly consistency in conditions, but we also determined that it was an issue of timing. Snowfall was low, and spells of warm temperatures abundant, but storms were just timed well to ensure that most snow quality issues were remedied by the weekend. Although the season was warm on average, we didn’t have many big rain events, and any that we did have seemed to be quickly covered by backside snow. There was indeed something special about the timing though, because somehow we had weekend after weekend of nice skiing with powder on Bolton’s 159″ of snow. The detailed reports below and the monthly ski summaries that follow, provide the specifics of how it all went down, and the frequency and distribution of P in the outings list really speaks to that theme of “surprisingly good”:
November: I’ll put November 2011 into perspective by looking at November 2010, in which the ski conditions were apparently poor enough that we didn’t ski once. Fortunately, that didn’t happen this season – even if just by a day. The near lack of snow in November 2010 could be considered demonstrative of typical November snowfall in the valley though, because up to that point it had truly been feast or famine since we moved to our current Waterbury location in 2006. However, this past November finally bucked that trend by coming in with 11.4″ of snow (128% of average) which is as close to “normal” snowfall as I’ve ever seen for the month based on my data. We had a couple of minor accumulating snowstorms early in the month, and then another mid month, but it was a storm near the end of the month that really produced 95% of our November valley snowfall. That storm dropped almost a foot of snow at the house, and got me to head up to Bolton Valley for some turns. In terms of skiing, options for catching the new snow atop a manmade base were rather limited because most of the local resorts were of course using their manmade snow to serve customers, but I headed up to Bolton Valley to see if the natural snow alone was enough for some turns. Since they don’t open until December, Bolton hadn’t yet made any snow by that point, but it turned out that the storm had dropped over a foot of snow up there, and it was dense enough that one didn’t need much of it to keep them off of whatever lay beneath. I enjoyed some decent turns, even if that outing wound up being the only one for the month. This past November was a decent step up from the previous couple of seasons with little to no snow, but we’ve still yet to have a very snowy November since the 2007-2008 and 2008-2009 seasons; both those seasons delivered roughly 20″ of snow in the valley, and plenty more in the mountains. The general seasonal trend of warm weather continued right through the month as well; although much colder than October on an absolute basis, November was even warmer relative to its long range average, coming in 5.1 degrees above normal at the National Weather Service Office in Burlington.
December: The first two thirds of December simply felt like a continuation of November; the pre-holiday period was hampered by above average temperatures, but the more notable issue was the absence of significant storms. The Northern Greens were holding their own thanks to numerous small snowfalls, and these events were definitely enough to get us into some powder skiing, but they weren’t enough to really build a deep base of natural snow. The last third of the month was really the highlight in terms of snowfall. As the all-important holiday week approached, Central Vermont northward finally got into some moderate storms. The localized nature of these storms was good for highway travelers from down south, and one could hardly ask for better timing of fresh snow for the holiday week. Storm 1 hit on Friday the 23rd, dropping roughly half a foot from Killington northward, storm 2 was on the 25th, centered on Stowe where they received over a foot, and storm 3 began on the 27th, with totals again topping out around a foot. The skiing was quite good, indeed excellent by the end of the week as the snow from the storms continued to pile up, but the lack of snowfall earlier in the month meant that the natural base depths weren’t there like they would normally be. Fortunately, some natural snow terrain was open, but certainly not the steepest stuff, and the natural snowpack was still just a bit too lean to spend much time in the trees. In any event, we skied eight times during that holiday stretch, a sign that there was definitely some good skiing. With all the new snow, our local area certainly had it a lot better than many places in the country did during the holiday week, so in that regard we were lucky. I’m sure business was still down at the Vermont ski areas in general, but people may have been hearing about the holiday snow that Northern Vermont was getting, because Powderfreak posted on Christmas Eve how lodging space was still very tight in Stowe. Despite the snow in the northern half of Vermont though, the general talk around the region was how poor and snowless it was in general, so I’m sure many places lost some potential visitors due to that. Even with those moderate storms at the end of the month, when all was said and done, we still ended up quite low on snowfall down at the house; the 24.7″ we received was just 59% of our average for the past six seasons. Temperature consistency/snow surface quality: With the slow start to snowfall, we didn’t even ski during the first weekend of the month, but we did get out for the other four. The second weekend was the one where there was no powder simply because there wasn’t enough snow. Temperatures were certainly above average as a whole (NWS in Burlington was +4.8 F on the month), but December mean temperatures start getting cold enough that even above average departures can still be sub-freezing and produce snow in the mountains . The third weekend of the month had some decent conditions at Stowe, and then the final two weekends sort of lose their definition with the big holiday week, and that period gets lumped together. Conditions for the holiday week were mostly wintry; strictly speaking though, the last weekend of the month did see a thaw, but in the context of the whole holiday week it was rather insignificant.
March: The first half of March felt like a continuation of that decent stretch at the end of February, even if we didn’t get any additional three to four foot storm cycles. Just a few days after the big February storm ended, another decent cycle came through heading into the 1st of the month, with close to a foot of additional snow at the northern resorts, and a foot and a half at the southern resorts. Amidst other freshening events, a storm on the 4th dropped about a half foot of snow, and then over a foot fell from a storm on the 9th that targeted the north-central resorts. The boost from the big February storm was felt in base depths and surface conditions, and you could feel that the season had really turned into what one would expect for March. Even as unseasonable warmth started to intrude and occasionally turn the powder wet through the first half of the month, there was usually enough time to get in turns for a good part of each day while the powder was still dry, and then more snow would come along to freshen things back up. The weather through that period was certainly on the warm side, but it was during the second half of the month when all hell broke loose with regard to temperatures. That expression is somewhat apt, because for March, it felt like that when five consecutive days of record temperatures with departures of +40 F hit the state from the 18th-22nd. Combined with the more moderate warmth during the rest of the month, the result was an incredible +12.2 F departure from the average March temperature at the NWS in Burlington. With almost no new snow in the valley during that warm second half of the month, March snowfall was a paltry 14.2″ at the house, just 60% of average. Temperature consistency/snow surface quality: The list of ski outings from above shows the trend here quite well, the first two weekends offered powder conditions, and from then on it was spring skiing. However, powder had been available for every weekend or holiday period since the middle of December by the point at which the snow conditions flipped, and that’s a commendable three-month stretch for such a season. Beyond the middle of the month, X was the only way to describe the powder conditions until we finally got to April. There was decent corn snow and great weather during that second half of March, but it was so warm that trail counts dropped rapidly at many resorts; even the huge snowpack gains made by the northern resorts at the end of February were lost as the snow depth at the Mt. Mansfield stake fell well below where it had been before the big climb. Despite the good spring skiing, it seemed like many resorts closed down simply because people had given up on winter by that point. The slow start and rapid end to winter seemed to take the wind out of everyone’s sails and, it had them looking to quickly put the season in the rearview mirror.
April: Temperatures for the month of April still came in above average (+1.2 F) at the National Weather Service in Burlington, but after the unprecedented warmth of March, that felt downright cool by comparison. Indeed April was more typical though, and some good skiing returned, even if the slightly warm temperatures kept the snow especially elevation dependent. With that trend, snowfall down at the house was almost insignificant, just 0.5 inches or 8% of average. That’s the least snowy April we’ve encountered in the six years that I’ve been monitoring snowfall at our location. Storms nailed the mountains with snow though, in the form of a minor event on the 4th of the month, then a big cutoff low dropping 2 to 2 ½ feet on the 9th. That snow was fairly dense and represented an unmitigated resurfacing of the slopes as one headed up in elevation. The skiing was great, at least in a Sierra Cement/Cascade Concrete sort of way where it doesn’t take much to cover whatever is below, but it would have been even better if the March warmth hadn’t deteriorated the snowpack as much as it did. With most ski areas closed after March sapped people’s interest in the season, plenty of great earned turns were made, but at the resorts that had stayed open, there was also some excellent lift-served skiing. April finished off with one final storm at the end of the month, which was nothing like the big one earlier, but it dropped about a half foot in the upper elevations and that was enough for some final powder skiing before we moved on to May. Temperature consistency/snow surface quality: While certainly not up to the level of April 2007, we did get to ski powder on all of our April days except April 1st. Most of what fell during the month for snow was rather dense, but it was still a nice reprieve to have fresh snow after the way March had gone. We only skied three of the five weekends that month, as half of our outings ended up being midweek.
May: After some tempering of the heat for April, Mother Nature was back at the stove for May, with a +5.3 F departure for the month at the NWS in Burlington. We didn’t have any accumulating snow in the valley, although that’s typically the case down at our elevation. There were actually no significant winter storms to speak of, but we did have one Vermont ski day on the 12th, enjoying the last of the corn snow up at Jay Peak. We took advantage of a Mother’s Day package that offered a chance to sample a lot of the new facilities up at the resort (water park, arcade, restaurants, etc.), and indeed taking in that smorgasbord of activities is an especially nice way to go when skiing is only going to be a minor part of a trip. Our other day in the month was actually out of state in New Hampshire on Memorial Day weekend, taking our traditional camping trip Auto Road ascent with the boys to ski the snowfields. The snowfields were somewhat on the lean side this year, but not bad considering what the region went through meteorologically during the winter season.
At the monthly level, the 2011-2012 ski season was a simply amazing stretch of positive temperature departures followed by even more positive temperature departures, and that trend has continued right into the summer, with June and July coming in at +1.9 F and +2.4 F respectively. August is currently coming in with a positive departure as well, and if it ends up staying that way, it will be the 17th month in a row in the positive departure streak for Burlington. Those departures are going to flip at some point, and it’s going to feel quite chilly by comparison. Despite that trend though, even when combined with below normal precipitation, the quality of the ski surfaces encountered this past season in Northern Vermont was quite good. I’m not sure if I’m willing to say better than average, since I don’t think surfaces were better than average at Bolton Valley, but I am willing to say that in our visits to Stowe this season, the typical on piste surfaces we encountered were actually better than the previous season. One thought is that the lack big storms in general also played out as a lack of notable rainstorms, which while generally infrequent in the heart of winter anyway, are likely more detrimental to the snow surfaces than more modest events with simply some mixed precipitation in the middle. The Northern Greens certainly showed throughout this past season that they have the ability to cover the back side of mixed precipitation events with additional snow quite effectively when there’s at least some moisture in the atmosphere to be wrung out. The fact that business was down somewhat at the resorts, may also have contributed to less skier traffic and slightly elevated on piste snow quality. Whatever the case, for a ski season that felt like an abysmal “perfect storm” of sorts with regard to temperatures and precipitation, 2011-2012 in Northern Vermont can certainly be described as “surprisingly good”.
