Lechuguilla Cave, is the 5th longest cave in the world and the deepest in the USA. But it is best known for its rare formations. Visit Wikipedia for great info and a few photos. It is located in Carlsbad Caverns National Park, New Mexico but access to the cave is limited to approved scientific researchers, survey and exploration teams and National Park Service management related trips. More incredible images.  For the Webshots page, click here....  The four images below are of the Lechuguilla Cave below...

Sandia Cave in Cibola National Forest Some history but no photos. A Geocities site has a photo where one can see that the entrances are in the side of a cliff. It's a ski area in the winter so little time was given to getting inside the caves.

Kokopelli's Cave Bed & Breakfast is a privately owned luxury cliff dwelling located north of Farmington, New Mexico near the Mesa Verde National Monument. This is not a natural cave, it was blasted to create work area. The scenery is extraordinary.
