Effigy mounds, ancient burial mounds, can resemble animals such as bears, eagles and long tailed underwater creatures. They are unique to the Driftless Area of southwestern Wisconsin and prominent along the lower Wisconsin River. “On His Own Terms” mentions them briefly, but they deserve much more attention because of their archaeological significance and unique formations. One of my favorites, Shadewald Mounds, shows a bison and eagle among other effigies and can be seen in Google’s aerial photos. They are located near the intersection of Highways 60 and 193 and north of Muscoda, Wisconsin. A series of conical mounds, thought to be a calendar for agricultural purposes, is preserved across Highway 193 to the west.
