Patent ID: 7727430

Claim:
A method for building a shelter of snow or ice crystals, comprising: a. positioning a snow support means in a generally horizontal orientation upon a construction surface, and b. securing said snow support means rotationally to said construction surface using anchor means, thus creating a generally horizontal axis of rotation, and c. securing said snow support means using angle support means, and d. packing snow to a predetermined thickness around exterior surface of said snow support means, and e. releasing said snow support means from said angle support means, and f. rotating said snow support means around said generally horizontal axis of rotation to expose at least a portion of said exterior surface of said snow support means, and g. repeating sequentially step c through step f until said snow support means reaches a substantially vertical orientation and one-half of said shelter is completed, and h. re-positioning said snow support means in a generally horizontal orientation and generally opposite the orientation of step a, and i. repeating steps c through f until shelter is fully enclosed, whereby said shelter is a predetermined surface of revolution created by rotating said snow support means about said generally horizontal axis of rotation.
