As my Covid-19 and winter hibernation has continued, a stalagmite outside the door to my suite has evolved. In the absence of anything else to look at, I have been noticing how it has changed.
This ice tower grows beneath the vent from the furnace to my home. As the hot air leaves the house, the cold outside air transforms the moisture in the air into water drops which immediately become ice when it is cold enough. I’m not sure how cold it has to be for that to happen, but I’m guessing about -10C. If anyone can provide a more scientific assessment, please let me know.
I first noticed this in March 2020 when I returned from California. At the time, it was a rounded chunky frozen deposit at the side of the house.
As this winter has continued to become more pandemic-ally isolating and cold, my stalagmite has grown taller, fallen down, regrown, and developed a twin tower.
Today the temperature reached 5C and I expect to lose my frigid phallic friend quite soon, so I thought I should record it for posterity. If this seems like an odd thing to celebrate, I should point out that in Edmonton we have experienced a 40 degree temperature change within a week. That does strange things to a person’s mind.
