Native American Site on University Libraries' Aerial Photography

Native American Sacred Site on University Libraries’ Aerial Photography

Archaeological researchers from Ball State University have identified a circular ditch near Yorktown, Indiana, as an earthwork of Native American origin according to the Muncie StarPress. The earthen structure was built about 2,000 years ago and measures 230 feet across. The circular ditch is 13 feet wide and three feet deep. The site lies just 150 feet from Indiana State Road 32 (Kilgore Avenue) just west of Nebo Road.

The site, dubbed Yorktown Circle, was probably used as a sacred site for ritual activities. No Native American artifacts have been recovered from the site, but researchers plan to nominate the circle to both the State and National Register of Historic Places.

The Delaware County Office of Geographic Information System (GIS) reported the site to Ball State researchers in 2005 after observing perfect circles on topographic maps and aerial photography.

Aerial photography of Delaware County published in 1941 available in the Geospatial Resources & Map Collection (shown above) clearly shows the site before many of the trees existed around the ditch. A Google Earth image of the current site (below) shows how trees have surrounded the circle.

Aerial photographs of Delaware County from 2005 are also available in the GRMC. Digital images can be accessed and saved or printed using the large-format plotter. The Collection also includes historic aerial photographs from other Indiana counties and several other states.

For more information about using historic and current aerial photographs, please contact or visit the GRMC on the second floor of Bracken Library.
