The Vanderbilt Archeological Site is an archaeological site located on the shore of Lake Oahe in Campbell County, South Dakota, near Pollock, South Dakota. The site contains the remains of a Native American Plains village which has been tentatively dated to about 1300 AD. Despite the fact that the site is subject to erosive destruction from wave action on the lake, it has been determined likely to yield significant information about the movements and living patterns of prehistoric Native Americans in the region. The site was declared a National Historic Landmark in 1997.
