Abstract
A method and apparatus for constructing a snow shelter are disclosed. A slip form allows snow or ice crystals to be compacted in situ in large continuous blocks. Each block is built upon the previous as the slip form is rotated incrementally around a generally horizontal axis (). The slip form is a convex shape. The convex shape, or profile, is tailored to the size and shape of the shelter desired. The resulting shape of the snow shelter is a surface of revolution of the profile of the slip form around a horizontal axis. Variations of the shelter's shape are explained herein. Various embodiments are described herein. Some of the advantages of the embodiments include: faster and more efficient construction, simple operation, and tailored size and shape of the finished shelter.
