The History and Importance of Igloos as Shelters in Cold Climates
TLDR Igloos, also known as snowhouses, are enclosed shelters made of hard-packed snow that have been used by the Inuit people for centuries. They are able to trap and insulate heat, making them significantly warmer inside than outside, and can be built by cutting large blocks of snow and shaping them into a dome structure.

Igloos are enclosed shelters made of hard-packed snow, called "snowhouses" by the Inuit, who are the most widely spread aboriginal group on the planet and prefer to be called Inuit rather than Eskimo.

The Inuit are a hunting-focused group of people who rely on hunting for food, and they have a unique condition called "kayak angst" where they become afraid of going out to hunt seals in a kayak due to a loss of sense of time and bearings.

The Inuit population in Canada has been growing, with as many as 68,400 Inuit in Canada by 2017, and igloos were never permanent shelters for them.
15:48
Igloos were not just single structures, but could be combined to create compounds and even cities, and they were able to trap and insulate heat, making them up to 40 degrees warmer inside than outside.

To build an igloo, you need to find wet-ish, hard-packed snow and use a snow shovel and saw to cut large blocks, which are then used to form the structure.
23:25
To build an igloo, you start by building a foundation in a circle and then work your way up, decreasing the size of the blocks as you go and shaping it at a slant; you can use sticks on the inside for temporary support until the dome is complete, and then you finish it off by plugging the central hole with a larger block and filling in the cracks with snow to create a smooth dome.
27:03
Building an igloo requires drilling air holes for ventilation to prevent suffocation, and while it is possible to bring a stove as long as there are enough air holes, it is recommended to build an igloo for fun and keep noxious fumes out of it.
