How many sites are there in South Dakota?
More than 19,000 archaeological sites have been recorded. These include campsites, buffalo kills, mammoth kills, rockshelters and caves, tipi rings, burial mounds, earthlodge villages, rock art, homesteads, townsites, mines, and cemeteries. Keep in mind, too, that archaeologists have only looked at a very small percentage of the land in South Dakota. A reasonable estimate for the total site count might be 150,000 to 300,000.
