Carlsbad Caverns National Park,USA.
This site is notable world-wide because of their size, mode of origin, and the abundance, diversity and beauty of the decorative rock formation within. On-going geologic processes continue to form rare and unique speleothems(decorative rock formation), particularly in Lechuguilla Cave. Carlsbad Caverns and Lechuguilla Cave are well known for their great natural beauty, exceptional geologic features, and unique reef and rock formations.
