An amazing cave Carlsbad United States

Carlsbad Cave is a National Park and wilderness area of Chihuahuan in Southeastern New Mexico, United States, near the base of the Guadalupe Mountains (mountain Sacramento segment). About 250 million years ago, surrounded by extensive reefs horseshoe-shaped limestone, shallow seas covered the region. Carlsbad Cave was founded in 1923 as a national monument, a special room-a national park in 1930, and was declared a world heritage site in 1995. At the bottom of the park, which has a surface area of 74 square meter kilos (189 pounds square meters), is 83 individual caves, including Carlsbad Cave, children's namesake. The Park also includes Rattlesnake Springs, a small enclave of about 5 miles (8 kilo meters) in the Southeast. This formation, called the Capitan Reef, found in Southeastern New Mexico and West Texas and including the Guadalupe Mountains National Park, just southwest of Carlsbad Cave National Park. After the sea evaporated, the constant dripping of acid ground water carved the large underground chambers, became limestone, gypsum and form large stalactites, stalagmites and other cave deposits range in smooth.
