Igloo Structure Diagram - Traditional Snow Shelter Design #141755 (License: Personal Use)

This black-and-white line drawing depicts a classic Inuit igloo, featuring a hemispherical dome constructed from tightly fitted, wedge-shaped snow blocks arranged in a rising spiral pattern. The entrance includes a low, tunnel-like vestibule to trap warm air and prevent wind from entering the main chamber. The structural integrity relies on compressive forces and the insulating properties of compacted snow.
