Igloo Structure Diagram - Traditional Inuit Snow Shelter Design #2365254 (License: Personal Use)

This black-and-white line drawing depicts a classic Inuit igloo constructed from precisely cut, wind-packed snow blocks arranged in a spiral, self-supporting dome. The entrance features a low, tunnel-like passage that helps trap warm air inside while minimizing heat loss. The interior is implied to be insulated and habitable despite subzero external temperatures.

Used on educational pages about Arctic indigenous cultures, survival shelters, or winter architecture; matches user intent for learning how igloos are built or visualizing traditional cold-weather housing.
