Rockhouse Cliffs Rockshelters

From Wikipedia Rockhouse Cliffs Rockshelters (12PE98 and 12PE100) are a pair of rockshelters in the far southern region of the U.S. state of Indiana. Located amid broken terrain in the Hoosier National Forest, the shelters may have been inhabited for more than ten thousand years by peoples ranging from the Early Archaic period until the twentieth century. As a result of their extensive occupation and their remote location, they are important and well-preserved archaeological sites and have been named a historic site.
