The given diagrams illustrate the construction of an igloo from snow.
Overall, this process includes five steps, beginning with cutting the hard-packed snow and ending with creating the entrance of the igloo.
At the beginning of the process, using a tool to cut the hard-packed snow into ideal snow block sizes, which are measured 3x8x15 inch. Next, the edges of the blocks are smoothed to attach them easily. After these blocks are smoothed, they are put in a circle building upward with many layers, which form a sphere shape. Before completing the igloo, they dig the hole under the wall to create an underground entrance. Finally, a slightly bigger block compared to the others are placed on the top to finish the foundation of the igloo.
The process continues with loose snow, shovel them onto the wall and pack into crevices to hold the blocks together. Smoothing the inside of the igloo by hand meticulously, and then if there is some extra snow, it needs to be shoved out. At the final stages of the process, the hole on the wall is digged to make space for the ground entrance before covering it with snow blocks to avoid snow can block the entrance.
