Digging a hole or trough will allow you to sit with legs hanging instead of cross-legged style. You can build with any snow shelter conditions (including sugar snow, slurpee type ice, depth hoar) allowing you to stay in the woods and out of the wind.

Takes less than 50% of the effort required to build a quinzhee or dig a snow cave of equivalent size. Build time is approx. 1-1/2 to 3 hours depending on snow quality and quantity. Shorter build times mean you will not be fatigued when complete and you will stay cool enough to prevent sweating and snow from melting on the outside of builder’s jacket.

Straps onto pack easily using supplied straps and buckles. Straps have auto release snaps allowing builder to keep gloves or mittens on. Slip form has auto release snaps to prevent form from breaking if it happens to fall full of snow. Snaps also help in assembly of form allowing builder to keep gloves on. Parts are made of bright colors to prevent loss of smaller pieces in snow. Support pole helps create the exact same ICEBOX® Igloo every time. (no guesswork)

An ICEBOX® igloo snow shelter is so strong, 3 people have stood on top of a completed igloo (not recommended).

The actual cross-section of a ICEBOX® igloo snow shelter is self-supporting because it forms acatenary curve. The same theory used in the flying buttresses of the cathedrals of Europe.

ICEBOX® igloo shelters are built by handling snow only once. (blocks are built in place) Builder is able to kneel or stand rather than lying down or kneeling like a snow caver. (Kneeling is only required for the first row.) You can extend the season since you only need 6 inches of snow to build and an igloo can be built from surface snow on summer glaciers. ICEBOX® igloos have been built on lakes with only 3 inches. (See North Dakota Minnesota photos.) Tall enough to facilitate standing up to stretch or get dressed.

Quiet, peaceful camping. No flapping in the wind like a tent. Just plain fun.
