The sun has returned and it’s glorious…sun dogs, halos, soft pastel light, and crisp shadows! It’s powerful and beautiful and I catch myself staring at the blinding light. We’re gaining almost 15 min of daylight every day now and it makes our jobs so much easier.
We are down to the last few weeks here – the spring crew is due to arrive at the end of this week! Things were looking good until we got slammed by a few big wind storms this week. We’re nearing springtime and the worst weather of the year. On Thursday we had sustained 35 knot winds and on Saturday they rose to 40-50kn sustained winds with gusts close to 60 knots…it’s hard to walk in that kind of weather and so much snow gets lifted into the air that it’s impossible to see more than a few feet. Temperatures also rise with the wind speed. Yesterday when it was 50 knots out it was -5F. Nice not to have as much frostbite concerns, but it’s sticky and relatively wet. I would take clear, calm, and -80F any day.
With so much snow being blown around monster snow drifts form. We had just cleaned up after the last good blow when we were hit again. There’s a giant moat around the shop and the Green House is buried to the roof on all but the south side. There’s still a bit of a moat there. The snow grains are tumbled by the wind, breaking into tiny shards and ground down to rounded grains. The wind pushes it through the tiniest hole – around door frames and through invisible cracks in window caulking and gaps around the walls. The building entrances and exits often comprise of two sets of doors – vestibules help to retain heat and also offer some protection against the persistent snow. Caulking and weather seals help, but in the extreme dry and cold they invariably crack and fail. With a little moisture they freeze to the door and rip off the frame. Constant chipping of ice and shoveling of snow wears down the material too – no matter what you do it’s a losing battle.
Thankfully the cold means there is very low water content in the snow and the super dry air evaporates any snow that gets into the buildings quite quickly. We don’t need to worry about mildew or mold here.
Even with the storms, this is my favorite time of the year; gorgeous sunrises and sunsets, a few hours of daylight, but still enough darkness at night to see the stars and auroras. We’ve had a few spectacular nights since sunrise…
