Measuring é¢7 x 32-it. in plan, the magazines have a maximum ceiling height of 13-ft. The two magazines are situated side-by-side on 50-ft. centers and share a common earth-fill blanket 150 x 70-ft. in plan which covers all but one end of each structure. Depth of the earthen blanket over the roofis 2-ft. A lU-ft. high by 12-ft. wide doorway provides the only access to each igloo. Louvered intakes adjacent to the doorway ventilate each structure.
