The diagrams show information about how an igloo is built. As can be easily seen, there are several distinct stages in the process of an igloo construction, beginning with finding a hard-packed snow area and ending with cutting the vents in the igloo’s wall or roof.
At the first step of the igloo building process, an area with hard-packed snow is required. Then, a snow saw is used to cut the snow into large blocks to build the base. The edges of these blocks are then smoothed with a saw. Once the smoothing process has finished, these blocks are laid around a circle, with the blocks stacking on top of each other. Next, a hole under the vail is dug to make an entrance. After this, a block of snow, which is slightly too large, is put into the opening on top of the igloo.
In the next step, snow is packed into all the crevices on the wall of the igloo. Subsequently, the internal surface of the igloo is smoothed by hand. Then, a hole is dug to form the entrance. At the final stage, vents are cut in the wall or roof to ensure that the air can penetrate inside the igloo.
