How to build an igloo

SAFETY FIRST: Ask an adult to help with tools you haven't used before.

The best-known snow shelter is the igloo. A brilliant use of engineering and resources, this simple dome made out of snow blocks is both strong and versatile.

THE MOST FAMOUS SNOW SHELTER

Arctic cultures such as the Eskimo and the Inuit developed it, and over time they came up with a hundred tricks to make the shelter more comfortable and sturdy, including making the entrance small (to help keep heat in) and melting the inside of the dome and letting it refreeze (for increased strength).

The earliest reference of igloo use came from the Vikings, who settled parts of Greenland and explored the eastern Canadian coast about a thousand years ago. They found natives living in igloos, but didn’t use them themselves because they considered the technology inferior.

History has proven otherwise, as the Vikings lasted for only about four centuries in the harsh climate of Greenland, while the native peoples are still carving igloos from the landscape today. Six hundred years after the tough Vikings were defeated by the tougher weather of the Little Ice Age, Boy Scouts still use the design of the igloo to keep warm.

BUILDING AN IGLOO

igloo1Diameter: Not to exceed 10 feet. Anything bigger would require a perfect dome, which is next to impossible to construct in the field.

igloo2Materials: Top layers of dry powder won’t work. Pack mounds of snow until they harden, or cut blocks of snow from the depth where your feet stop sinking.

igloo3Entrance: Build a door in the ground, about 18 inches lower than the ground inside the igloo, and tunnel below the wall into the igloo. For proper ventilation, never seal or close the entrance.

igloo4Walls: Cut the blocks into a spiral layer, leaning one block against the next. Keep the interior wall smooth so moisture can run down the side of the wall, instead of dripping from the ceiling. Include a vent hole to allow for better circulation.
