Carlsbad is located in Southeastern New Mexico, straddling the Pecos River on the edge of the Guadalupe Mountains. The town, which is the county seat of Eddy County, has a population of 26,138 (2013 census), and was named after the European spa Karlsbad, because of mineral springs located north of the city that were believed to have medicinal value. It is a popular tourist destination as the Carlsbad Caverns National Park is located here, as is the Living Desert Zoo and Garden State Park, with several other national parks and forests nearby. Carlsbad has been known as a top producer of potash since 1925, when deposits were found here, and the mining of it still takes place today. New Mexico State University has a branch campus here with an enrollment of approximately 2,000 students, making Carlsbad a college town.
