The Chihuahuan Desert, as well as the city and state, are all derived from the Nahuatl (nao-wat) word, Xicuahua (shee-kah-wah). Some believe the word describes “the land where the rivers meet” while others use it to describe “a dry and sandy place.” Just considering the topography, they’re both correct. The World Wildlife Fund has declared our home one of the most unique arid regions in the world. Not only is our desert the largest in the Western Hemisphere (larger than the state of California), but it’s also the most biologically diverse desert on this side of the world.
