That’s an arch made of snow, look at the grace, and the beauty, and the leaning of it towards one side. Seems like a work of snow art that took hours to make, only to be destroyed by nature. Oh well, here are some instructions on how to make it. And here are some nice photos on how it was made:
Making the base with what looks like plastic tub, nice. We used a garbage can for our snow slide.
They used the bad bricks to hold up the arch as it was made. Good thinking, next they should boil them down and make some coffee with them or something. Maybe coat the arch with ice. We did that to our slide, it lasted for ages because of it.
The final test, remove the supports and hope the arch lives. Theirs does, yay for them. But victory is short lived, because the heat soon makes its mark and destroys the once graceful arch. Oh well, here’s a nice video of the arch failing completely:
