The idea of building an igloo came shortly after the first snowfall. All the kids of our street started to build snowmen and forts.
The problem with snow in the Yukon is that after the first snowfall, it’s usually very cold and the snow is very dry and falls like powder when you try to make a simple snow ball.
To circumvent that fact, I decided to build a wooden crate and compact snow inside. The effect of pushing snow flakes together brakes their protuberances and stick their cores together making for a solid icy block.
Another challenge was to build the roof a the igloo. Past a certain angle, the blocks tend to collapse. The solution was to cut the side of the blocks at an angle and hold the first and last block of a row. The last block serves as a key and holds everything together.
