How Native Americans Built & Lived In Semi-Underground Homes at -30°C (-22°F )

This episode explores how Native American tribes engineered semi-underground homes to survive extreme winter cold where surface shelters would fail. It explains how digging into the earth provided natural insulation, stabilizing indoor temperatures even when outside conditions dropped to –30°C. The film breaks down construction methods using timber frames, packed soil, and central hearths to trap heat and block wind. It also shows how daily life—sleeping, cooking, and food storage—was organized around thermal efficiency. These homes were not temporary shelters, but carefully designed systems built for long-term winter survival.
