The Lake Castrovalva area of Lechuguilla (cave) in Carlsbad Caverns National Park, New Mexico, is very special. It is abundant in very delicate and unique cave formations, and for this reason it is very rarely visited. These formations are simply perfect and pristine. Here, an American explorer admires a fine set of rimstones and gours. For millions of years, the cave has been sealed off from human and animal interaction. Lechuguilla is a very beautiful and highly protected cave. Access is very strongly controlled and only given to experienced cavers with specific scientific or exploration goals within certain parts of the cave.
