7/30/2008: It was on this day, July 30, 1992 near Golden Valley that the State Historical Society of North Dakota acquired a rare collection of 95 stones. Taken by themselves, these stones were nothing special; similar to any number of rocks found throughout the state. However, left where they were found and undisturbed they formed the shape of a large turtle; twenty-one feet from head to tail and eleven and a half feet wide.
