The pleasure lies not in discovering truth
But in searching for it.
Leo Tolstoy
Winter has arrived in Anchorage. Fall was one of the warmest on record and it just seemed to never cool down. The grass remained green. It was time to progress to winter according to the usual standards. I remember in 1995 we could ski out our door, on 5 October. OK I admit a bit of any anomaly but I declared that is the way it should be. Has not happened since and since the turn of the century, winter is often questionable. It is depressing. We had the SAD light out every morning, and the sunrise came later every day. Finally a trip to Seattle, and when we returned there was snow, and it cooled down. Amazing how our spirits rose. Not only was there snow, and I mean usable skiable snow, but it provided white to reflect the light at night and brighten things up. Our mental attitude vastly improved. Then it got cold, meaning winter was finally here. I say winter consists of three things – dark, cold and snow. If you only have dark that just does not cut it.
I volunteer at the ski jumps, and making snow in the fall is a big deal, given the last years of warming trends. Last year, being one of the worst on record for warmups, we had to make snow 4 times, as it melted 3 times with horrible warmups, warm temperatures, and often wind, and sometimes rain, destroying the hard work.
This year though it got cold and the small downhill ski area near here (Hilltop ski area) and next to the ski jumps began blowing snow. Making snow is a process of spraying huge amounts of water under pressure to build the piles of snow needed. The temperature has to be below 25 degrees F. ( about -6 C) otherwise just water sprays out. The colder the better. At the ski jumps we use the Hilltop water from a local creek but there is only so much they can pump. They have a much larger area to cover and it takes a lot of time, as well as they require almost a meter to cover the lumps, bumps and rocks in the ground, as well as provide enough for potential meltdowns later. Their business model is a bit different than ours so they get preference, as it is their water. (They have to make money, we have to provide fun and activity) Hence when they get enough to cover enough area to open the area for a run or two of skiing, they then let us use one of thirty water connections. It works out good, as we need 3-4 days to cover our area and they require weeks. Good neighbors.
As Hilltop made enough snow for one good run, it was time for us, and it warmed up. Ugh. All snow making ceased. The natural snow and snow they had made remained but no snow making, until it cooled off. Temps went up to the mid 40s (8-9 C)
But after weeks of fretting and worrying, it cooled off again this time cold. The director of the ski jump program, Zak, gave clearance to start making snow. When one starts blowing snow it is a continuous process. Lay out the hoses and electrical cord, and get the snow gun in place. That takes about an hour, as the hoses are 50-150 feet long (15-45 meters) and we lay out nearly 500 feet (150 meters). When the water starts flowing at up to 100 gallons a minute (375 liters/ minute), if for whatever reason it gets turned off or stops flowing it can freeze in the hose within minutes, thus once you stop making snow it is continuous because to shut down is about a 2 hour process, taking hoses back and hanging them to drain and dry.
I love volunteering because I get to do useful work and get to do all sorts of stuff I never get to normally do. Plumbing, electrical, carpentry, design, and see the smiles and joy as the kids reap the rewards. Not only physical but mentally with figuring out how things work. We have what one calls a shoestring budget, and everything is very dear in terms of money, hence we are the crew.
The mental aspect is great as we have to not only figure out how to do something, but how to do it safely. Working with heavy equipment, in the cold has its potential problems. Not only is the water at way below freezing temperature, but the snow gun uses 440 volts and has its issues also, as well as the ski jumps have a 35 degree slope to contend with.
Over the years Zak and I have learned some tricks to make it safer and easier, and less tiring. Used to be when we blew snow one had to go and ski pack it closely after it was made, otherwise a hard crust would form over hollow snow. Then we obtained a snow cat 12000 pounds (5400 Kg) of tracked compaction and grooming capacity. One can blow snow into a pile and push it around and smooth it out. Wonderous labor saving device. And hilltop ski area has a night crew so the past two years Zak and I can set the gun for the night and they have offered to watch it. (Requires a minimum of every 2 hour verifying the water is flowing correctly and the fan and compressor are working.) Hence we can go home and sleep and not have to catnap on the floor, as in past.
But we began setting up last Thursday and began blowing on Friday. We worked the gun, moving it around as necessary to the appropriate location. It is easier and more efficient to blow in places needed, rather than drag it around. We hoped to be done by Tuesday.
All worked well, and the small 10 and 20 meter jumps were covered with about a foot of compacted snow (30 cm) . Zak, Natasha (another ski jumping coach) dragged the snow gun up the 40 meter hill pulling the water lines and electrical extension cord along with. It took a huge amount of work to get it down as it had to be pulled down through the new snow. Then the 65 meter hill ( which has a length of 120 meters, plus the runout area).
Monday we started working it up the 65 meter hill. We were counting down the distance remaining to go. Then with 35 meters to go (moving it 20 meters at a time) I was working on the hill pulling the water and electrical lines out from under the snow, when there was a loud pop, and the electricity cutoff, only water shooting out of the snow gun. I climbed the hill and turned on the power again, returning to get the lines out from the area now being covered by ice. This time though when I grabbed the extension cord it popped and sparks flew. I later told the boss of Hilltop ski area I was getting bored and his response was “well 480 volts will give you some excitement”)” this time it did not restart as the system had shorted and fuses blown. We had to shut down. Turn off the water, and drain hoses and fix extension cord.
It took all day Tuesday to repair the line as one has to work systematically in order to find the correct area. Turns out it was on the cord of machine and could not get the broken piece down hill or inside to warmth, thus had to work outside in temperatures around -4 F (-20 C) with fine detail work. Fun! or what I call fun! Why would one sit on a beach with nothing to do when you can do this.
It was a great relief after several trys when we got new hoses and plugged in the machine and it worked blowing snow. Again we could stand under the new snow coming out of machine being blown at 30-40 mph (50 – 60 km/hr). One comes away covered in an ice layer.
We managed to get it blown Tuesday evening and set it up to blow a final pile of snow for areas missed. Wednesday Zak shut it down. Afraid I was totally exhausted.
And now winter is in full swing. Of course could use some natural snow, but barring any meltdowns we are set. Past week and forecast for next week is good with temps around zero (-20 C) . Am happy have figured out how to dress for it and let the fun begin. As I walked a trail yesterday there were bikers and skiers out just enjoying the wondrousness of winter. Supposed to be northern lights out last night but my eyelids were closed.
Now I need to go for another walk while the sun is at its peak of 6 degrees above the horizon.
