Kartchner Caverns State Park is a state park of Arizona, featuring a show cave with 2.4 miles (3.9 km) of passages. The park encompasses most of a down-dropped block of Paleozoic rocks on the east flank of the Whetstone Mountains.

The caverns are carved out of limestone and filled with spectacular speleothems which have been growing for 50,000 years or longer, and are still growing. Careful and technical cave state park development and maintenance are designed to preserve the cave system
