The diagram illustrates the process of biulding an igloo.
Overall, there are 13 main steps in this process, beginning with cutting hard packed snow and endding with culminating in covering the entrance hole with snow blocks.
At the first main step, hard-packed snow is cut by snow saw to form the large blocks at the base. The snow block size is 15 in height, 8 in length and 3 in width. Next, the edges of these blocks, which like cubes, are smoothed to build the base which has a round shape. At the next stage, the walls are dug to create a hole to make an entrance for the igloo and a block is slightly large for the last opening on top. At the eighth stage, snow is packed by the spade into all crevices or gaps between these blocks.
Then, snow is shovelled onto the outside of the igloo and is packed into all crevices while the internal surface of the igloo is smoothed by hand. Any excess snow is also removed from the inside of the igloo. And finally, a hole is dug in the shape of the entrance, and is then covered with snow blocks to complete the igloo.
