Abstract
A pair of molds or forms for constructing a geodesic igloo are described. One of the molds forms a hexagonal block of snow; the other, a pentagonal block. An icosahedron igloo with frequency 3 or 6 is constructed by shovelling snow into the molds, compacting such snow, and then carefully placing the compacted block of snow onto the igloo being constructed.
