River Hills, native American Burial grounds

In 1963 The Science Museum of Minnesota excavated a burial site along the river bluffs across the river from the Black Dog power plant to the south of the Black Dog Village site. The location was the River Hills housing development—a development designed to contain at least 1,000 homes—in Burnsville, the next township south of Eagan along the Minnesota River. The first evidence of human remains was uncovered by a bulldozer operator who was grading the site. Over eleven days seven burial pits containing what were estimated at the time to be at least 56 human beings were excavated. Many of these were bundle burials dating to thousands of years ago. Later work by anthropologist Marcia Regan in a 1990 report estimated that the remains of 36 individuals were included in what was found at the River Hills site.
