Superquark - S22E04: Episode 4

The fourth episode of Superquark features another documentary from the Ushuaia Nature series: "Worlds of Crystal." Nature conceals secret, breathtaking places that are otherwise inaccessible to us, locations that require expertise, courage, and specialized equipment to explore. Tonight, we join the Ushuaia crew as they venture into some of these realms: deep within the Earth’s crust, navigating through caves, tunnels, and vast underground rivers, surrounded by extraordinary crystal formations. Our journey takes us into the canyons and caverns of Mexico, before arriving at a tiny island in Colombia to witness a spectacular deep-water dive. On this small island, we will encounter a rare and delicate creature: the glass frog. Scientists and naturalists join Nicolas Hulot on this fascinating expedition.
