The diagram illustrates the process that is used to build an igloo from snow.
There are five main stages in this process, starting with finding an area covered by hard-packed snow and culminating in covering the entrance hole with snow blocks.
As can be seen from the process, after a surface of hard-packed snow is found, a snow saw is used to cut large blocks to the appropriate size to build the base. The edges of the blocks are then smoothed with the saw and are placed in a circle, and a hole is dug under the wall to make an entrance. Next, a slightly over-sized block is precisely shaped and placed on the top of the igloo.
Out of the remaining steps, snow is shoveled 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.
