Igloo Structure Diagram - Traditional Inuit Snow Shelter Design #1397429 (License: Personal Use)

This black-and-white technical illustration depicts a traditional Inuit igloo, built by stacking carefully cut snow blocks in a self-supporting spiral dome. The structure includes a low, arched entrance tunnel that helps trap warm air inside and prevents wind from entering directly. Shading and perspective lines emphasize the three-dimensional curvature and block layering essential to its structural integrity.

Used in educational content about Arctic indigenous architecture, survival shelters, or winter science lessons; targets students, teachers, and outdoor enthusiasts seeking visual understanding of igloo construction principles.
