ERO conducted a geophysical survey of approximately 19 acres in an area adjacent to the Big White/Alderin Creek site in Mercer County, North Dakota, along the upper Missouri River. The site was believed to be the location of the historic village of Big White, a Mandan chief visited by Lewis and Clark in 1806. Basin Electric Power Cooperative contracted ERO to examine the archaeological potential of the site and evaluate the results against future development plans. The geophysical data indicated 30 anomalies that are likely buried archaeological features.
