Quick Answer
Unique igloo designs to try include the spiral, quinzhee, and snow trench igloos, each with its own advantages and challenges.
Traditional Igloo Design
The classic igloo design is the most well-known and widely used. It involves building a dome-shaped structure using blocks of snow, typically 12-18 inches thick. The blocks are stacked in a spiral pattern to create a strong and sturdy structure. To build a traditional igloo, start by creating a foundation of packed snow, then begin stacking blocks in a spiral pattern, overlapping each layer slightly to create a strong bond. The dome shape helps to distribute the weight evenly and provides excellent insulation.
Spiral Igloo Design
The spiral igloo design is a variation of the traditional design, where the blocks are stacked in a continuous spiral from the base to the top. This design requires less snow than the traditional design and can be built with a smaller amount of material. To build a spiral igloo, start by creating a foundation of packed snow, then begin stacking blocks in a spiral pattern, gradually increasing the diameter as you climb. This design is ideal for building in tight spaces or on uneven terrain.
Quinzhee Igloo Design
The quinzhee igloo design is a simple and easy-to-build shelter that uses a pile of snow as the primary structure. It is built by piling up a large amount of snow and letting it settle, then digging out a hollow space in the center. The quinzhee design is ideal for emergency situations or when building materials are scarce. To build a quinzhee igloo, start by piling up a large amount of snow, then let it settle for a few hours, allowing the snow to compress. Use a shovel or a pickaxe to dig out a hollow space in the center, creating a small entrance and a larger sleeping area.
