Seven hundred feet below New Mexico’s Guadelupe Mountains, the air is cool. The tiniest hint of a breeze tickles the skin, and apart from our breathing the cave is entirely silent. The stalactite formation shown here is known as The Chandelier, formed over thousands of years by the slow deposition of calcium carbonate in dripping water.
