What is Carlsbad Caverns National Park?
Carlsbad Caverns National Park is located in southeastern New Mexico, near the Guadalupe Mountains. Established in 1923, it became a national park in 1930 and a UNESCO World Heritage site in 1995. The park covers 73 square miles of the Chihuahuan Desert.
The park features 83 caves, including the notable Carlsbad Cavern. About 250 million years ago, the area was a shallow sea surrounded by a limestone reef. Over time, acidic groundwater carved out the massive underground chambers, creating stalactites, stalagmites, and other unique formations.

Where is Carlsbad Caverns National Park located?
Carlsbad Caverns National Park is situated in the Chihuahuan Desert in southeastern New Mexico, near the base of the Guadalupe Mountains. The park was initially established as a national monument in 1923, later becoming a national park in 1930. In 1995, it was designated a UNESCO World Heritage site. The park is home to 83 individual caves, including Carlsbad Cavern, from which the park gets its name.

What are caverns, and why are they important to this park?
A cavern is a large, naturally formed underground chamber with an opening to the surface.
Carlsbad Caverns National Park in New Mexico contains 83 individual caves, including the Carlsbad Cavern for which the park is named. The caverns formed from the dissolving of limestone by acidic groundwater, creating unique geological formations. The caverns are important to the park because they attract millions of tourists each year, boosting New Mexico's economy.

What kinds of rock formations can you see in Carlsbad Caverns?
Carlsbad Caverns National Park features a variety of cave deposits, also known as speleothems, which create the beautiful and unique formations within the caves. These formations include stalactites and stalagmites, which grow over time from dripping water. Flowstone, another common deposit, creates sheets of calcite along walls and ledges. The park is also home to rare formations such as the Giant Dome, Twin Domes, delicate rimstone dams, and the Monarch, one of the world’s tallest columns.

What animals live inside and around the caverns?
Carlsbad Caverns National Park is home to diverse animal life both inside and around the caverns. The park's wildlife includes mule deer, coyotes, bobcats, rattlesnakes, and pumas (mountain lions).
A colony of approximately one million Mexican free-tailed bats inhabits the Bat Cave section of the caverns during the summer. Each evening at sunset, they emerge from the cave entrance to feed in the surrounding area.

How were the Carlsbad Caverns formed, and why do scientists find them interesting?
Carlsbad Caverns formed about 250 million years ago when a shallow sea, surrounded by a massive limestone reef, covered the area. After the sea evaporated, acidic groundwater carved out the underground chambers, converting limestone to gypsum and creating stalactites, stalagmites, and other unique formations.
Scientists find the caverns interesting because they provide a stable environment where the slow growth of crystals is uninterrupted, leading to the development of unique speleothems. These formations result from the deposition of chemical sediments like calcite, gypsum, and other minerals from dripping, flowing, or seeping water. Some researchers believe that the caverns may have originated from dissolution with sulfuric acid.

Carlsbad Caverns National Park, area of the Chihuahuan Desert in southeastern New Mexico, U.S., near the base of the Guadalupe Mountains (a segment of the Sacramento Mountains). It was established in 1923 as a national monument, designated a national park in 1930, and proclaimed a UNESCO World Heritage site in 1995. Beneath the park, which has a surface area of 73 square miles (189 square km), are 83 individual caves, including Carlsbad Cavern, the park’s namesake. The park also includes Rattlesnake Springs, a small enclave about 5 miles (8 km) to the southeast.
About 250 million years ago, a shallow sea ringed by a vast, horseshoe-shaped limestone reef covered the area. This formation, called Capitan Reef, is found in southeastern New Mexico and western Texas and includes Guadalupe Mountains National Park, just southwest of Carlsbad Caverns National Park. After the sea evaporated, the constant dripping of acidic groundwater carved out the massive underground chambers, converted limestone to gypsum, and formed enormous stalactites, stalagmites, and other cave deposits ranging from the delicate to the bizarre.
Pictographs near the entrance to Carlsbad Cavern give evidence that Native Americans knew of the site 1,000 years ago, but it wasn’t until the 1880s that nearby settlers rediscovered the location and began mining it for bat guano to be used as fertilizer. One of the miners, James Larkin White—who claimed to have discovered the cavern—explored the cave further and began giving tours lit by kerosene lanterns, lowering the curious to a depth of 170 feet (52 metres) in bat-guano buckets. White also guided early scientific expeditions into the caves, including a major reconnaisance conducted for the U.S. Geological Survey in 1924.
Carlsbad Cavern has a labyrinth of underground chambers, including one of the largest ever discovered. The total length of the rooms and passages is still unknown, but the explored part of the main cavern is more than 30 miles (48 km) long, of which 3 miles (5 km) are open to visitors. Of the three major levels, the deepest is 1,027 feet (313 metres) belowground. Visitors can walk or take an elevator to the 755-foot (230-metre) level and explore the Big Room, which measures about 2,000 feet (610 metres) long and 1,100 feet (335 metres) wide at its greatest extents and has a ceiling that arches 255 feet (78 metres) above the floor. Found within are the Giant Dome, a stalagmite 62 feet (19 metres) tall; the Twin Domes, only slightly smaller, superbly proportioned and delicately fluted; and the so-called Bottomless Pit, which is some 700 feet (210 metres) deep. During the summer a colony of about one million Mexican free-tailed bats inhabits a part of the caverns known as Bat Cave; each evening at sunset they swarm out of the cave’s entrance to feed in the surrounding area.
To the southwest of Carlsbad Cavern, within the park, is Slaughter Canyon Cave, with the Monarch, one of the world’s tallest columns (89 feet [27 metres]), and a delicate rimstone dam (natural dam formed by the accumulation of calcium carbonate). Near the northern border of the park is Lechuguilla Cave. Since 1984, when exploration of Lechuguilla began, more than 100 miles (160 km) of passages have been surveyed. It is the fifth longest known cave in the world, the third longest in the United States, and it contains underwater formations unlike those found anywhere else in the world. In 1993 Congress passed legislation establishing a cave protection zone of about 10 square miles (25 square km) around Lechuguilla.
The park’s surface area is a sanctuary for such native plants as yucca, ocotillo, Texas black walnut, and desert willow. Park wildlife includes mule deer, coyotes, bobcats, rattlesnakes, and pumas (mountain lions).
