This photo is of full-sized humans next to crystals

“.. up to 36 feet long and weighing 55 tons. Scorching-hot temperatures that could kill a human after just 15 minutes of exposure. Those are the descriptions of a newly-discovered cavern deep underground in Mexico that National Geographic is calling “one of the greatest natural marvels on the planet.”

This Sunday, October 10, the National Geographic Channel will air “Into the Lost Crystal Caves,” a two-hour special on the discovery and exploration of the Cueva de los Cristales, the Crystal Cave. More details, photos, and video on National Geographic here: http://channel.nationalgeographic.com.”
