The illustration demonstrates the process of igloo generated by snow.
Overall, there are eight steps in the sequence: starting with sawing snow and ending with completing igloo.
Regarding the first four steps, initially, hard packed snow is collected on the street and sawed into different shapes. After this, sawed snow is arranged round four metres long and those shapes are placed with two large block floors and two small block floors. Subsequently, on the top of the igloo is placed a small round, which makes a full igloo and prevents bad effects from the environment.
Turning to the remaining steps, people use loose snow to decorate the exterior with two metres height of igloo. In the following steps, people continue to build a gate in front of the igloo. Then, the igloo is decorated with air holes inside of this, so it becomes more beautiful and sturdy to use and decorate.
