This mound and two adjacent mounds were built for burials, probably by the prehistoric Woodland Indians, who perhaps began entering Wisconsin about 2000 BC and lived here until modern times. The Potawatomi who left Waukesha in 1886 were never mound-builders. Waukesha County once had 411 mounds, and the city had 55 on 11 sites. This mound was excavated in 1850, and beneath ground level were found decayed fragments of a human skeleton with head to the west, decorative pipes, and pieces of shell and pottery.
