Igloo Structure Diagram - Traditional Arctic Snow Shelter Design #2365290 (License: Personal Use)

This illustrated igloo depicts a traditional Inuit snow shelter constructed from compacted snow blocks arranged in a self-supporting spiral dome. Key features include a low, curved entrance tunnel that minimizes cold air infiltration, an elevated sleeping platform inside for better insulation, and a small ventilation hole at the apex. The design leverages snow’s insulating properties and structural integrity to maintain survivable interior temperatures even in extreme Arctic conditions.
