Carlsbad Caverns National Park contains the most spectacular show cave in the USA. It is located in the Guadalupe Mountains along the border between New Mexico and Texas, a region well known for its large and well-decorated caves and world-class exposures of Permian rocks. In addition to the Carlsbad Cavern, the Park contains several other large caves, some of which are also open to the public. They have long been inactive, and many details of their origin are debated. They were formed in several stages, including early dissolution by mixing of fresh groundwater with deeper brine, and late enlargement by sulfuric acid as a result of oxidation of rising hydrogen sulfide. This latter process was concentrated at and above the water table. Patterns of limestone dissolution and mineral precipitation have been strongly influenced by air circulation. Management issues include protecting the caves and their environment, while providing safe and educational public access and dealing with neighboring land-use pressures.
