Quick Answer
The ideal height for igloo walls is around 6 to 8 feet, allowing for stability and snow load distribution. This height also enables easy entry and exit through the doorway. The height can be adjusted slightly depending on the snow conditions and personal preference.
Building Igloo Walls
When constructing the walls of an igloo, it’s essential to maintain a consistent height to ensure stability and even snow distribution. The recommended height is around 6 to 8 feet, which provides a comfortable entry and exit point. To achieve this height, start by digging a trench for the foundation, about 2-3 feet deep and 6-8 feet long. Then, begin stacking blocks of snow, starting from the foundation and working your way up.
Stacking Snow Blocks
To stack the snow blocks efficiently, use a technique called “quincunx” or “pyramidal” stacking. This involves placing each block at a 45-degree angle, with the edges pointing inward. This technique allows for maximum stability and minimizes the risk of collapse. Start by placing a block at the base, then stack the next block on top at a 45-degree angle. Continue this process, working your way up the wall, making sure each block is securely in place before adding the next.
Finishing the Igloo Walls
Once you’ve reached the desired height, you can start to shape the walls and create a smooth surface. Use a shovel or your hands to pack the snow tightly, making sure there are no gaps or weak spots. To add extra stability, you can create a “keystone” block at the top of the wall, which helps to distribute the weight evenly. This block should be slightly larger than the others and should fit snugly into place.
