The Fascinating History of Carlsbad Caverns

The formation of Carlsbad Caverns dates back millions of years, with the park’s limestone deposits originating from the remains of an ancient reef system. Over time, hydrogen sulfide gas from deep oil deposits combined with groundwater to create sulfuric acid, which gradually dissolved the limestone, resulting in the formation of the caverns. In addition to their geological significance, the caves also hold a rich cultural history, with evidence of human presence dating back to over 12,000 years ago. Native Americans, such as the Mescalero Apache, were among the first to explore and utilize the caves, leaving behind artifacts and pictographs as evidence of their presence.

The modern history of Carlsbad Caverns began in the late 19th century when European settlers took interest in the region’s vast mineral resources. In 1898, James Larkin White, a cowboy and eventual park ranger, discovered the entrance to Carlsbad Cavern after noticing a large number of bats emerging from the cave. White’s discovery led to the first organized exploration of the cavern, and by the early 20th century, the cave gained popularity as a local tourist attraction. Recognizing the need for preservation and conservation, President Calvin Coolidge signed a proclamation establishing Carlsbad Caverns National Monument in 1923. The park was later redesignated as a national park in 1930 and was inscribed as a UNESCO World Heritage site in 1995.
