Naica: Secrets of the Crystal Cave (2008 TV Movie) 6 of 10 stars ⭐

This is a short doc about the crystal cave that was discovered in Mexico around 2000. Miners for silver and lead, tapped into a flooded cave full of massive crystals. The crystals have been growing to massive sizes for over 400,000 years, and they are amazing! The only problem? Thanks to a magma chamber, deep under the Earth, the cave is too hot for humans. Special suits were designed for the scientists, and even with them, people can only stay in the cave for twenty minutes at a time. NASA scientist, Dr. Chris McKay, who studies extremophiles, was on hand trying to find life in the crystal cave. He also studies off world life, and how it would develop in hostile environments. The crystal cave is a perfect place to study these types of biosystems. The cave can only be studied for a short time, because by pumping the water out of it, the crystals stopped growing. It also weakened them, and put them at risk for collapse. This documentary was a brief, but beautiful glimpse into one of Earth's wonders.
