I would like to happily welcome you all in joining me on a tour of Carlsbad Cavern. Carlsbad Cavern is a United States National cavern located in the Guadalupe Mountains of southeast New Mexico. The cave was dissolved along cracks and faults in the limestone rock by sulfuric acid. The limestone was laid down about 250,000,000 years ago, as part of a reef complex along the edge of an inland sea. Seventeen to 20,000,000 years ago, the ancient reef rocks that had been buried under thousands of feet of younger rocks began to lift upwards. This historic park is very special because it contains more than 119 limestone caves. The cavern is special because of its many famous rock structures and its enormous room known as the “Big Room.”
