Igloo Diagram - Traditional Inuit Snow Shelter Structure #141768 (License: Personal Use)

This black-and-white illustration depicts a classic igloo built using precisely cut snow blocks arranged in a spiral, self-supporting dome. The structure features a low, tunnel-like entrance that reduces heat loss and blocks wind, while the interior curves upward to maximize space and thermal efficiency. Such designs reflect centuries of Indigenous Arctic knowledge in cold-weather shelter engineering.
