Exploring Caves: Where Are America's Caves?

Most of the caves in the United States are limestone caves. They cluster along the Appalatian Mountains; borders of Minnesota, Wisconsin, Iowa, and Illnois; boundary of Missouri and Arkansas; down Ohio, Kentucky, Tennesse, and Alabama; and south central Texas. There are also sprinkles of limestone caves at the western U.S.

There are much less lava caves in the U.S. in comparison to the limestone caves. Most of the lava caves reside on the western U.S., such as Washington State, Oregon, Calfornia, Idaho, Nevada, Utah, Arizona, and New Mexico.

Gypsum caves, which are fewer than lava caves, can be found in northern Texas, New Mexico, and few other states on the west coast.

There are few caves in other forms. They can be found all over the United States.
