It is a common misconception that archaeologists are only interested in Indian history. Archaeologists are interested in the human story. In North America, that involves both the Indian and the Euro-American cultures. In other parts of the world, archaeologists study the history of the people who lived there. As for dinosaurs, those studies are left in the capable hands of the paleontologists.
Archaeologists are apt to use odd terms for common objects.
One such is the term cache pit . This is nothing more than the French term for a storage pit. Many of the earthlodge villages of the Plains Village peoples, and later the Arikara and Mandan, were fortified by a deep ditch and a log stockade wall, also known as a palisade. Although many sites are accessible to the public, most do not offer anything to see. Other sites which are open to the public and have interpretive signs, including Fort Pierre Choteau, Fort Randall, mounds at Oakwood Lakes State Park, and prehistoric and historic sites at Hartford Beach State Park.
