S2 E12 | Extraterrestrial Lairs

Across continents and cultures, remote caves, mountains, and subterranean labyrinths have long been regarded as secret refuges-hidden homes of gods, giants, and beings not entirely human; Australia's Black Mountains are steeped in tales of vanishing travelers and otherworldly guardians, while Native American legends link the Oregon Caves to Bigfoot-like creatures who retreat into underground sanctuaries; ancient Greek myths tell of troglodytes; sky-born beings said to dwell in caverns.
