Shadewald Mound Group (sometimes called Elder Group) is an incredibly well preserved group of Native American effigy mounds. Thanks to Frank Shadewald, who purchased the land with the sole purpose of preserving the mounds, there is no other group of mounds that could compare with Shadewald as far as the state of preservation goes. There are two clusters of mounds out there. One is located on top of Frank’s Hill and consists of, among others, a raptor and a bison effigies. The other cluster is on top of the hill just across the road from Frank’s Hill (below). It consists of 12 conical mounds in almost perfect linear formation within the same distance of one another. It is thought that the mounds have some calendar meaning. Although its unlikely the Native American and Roman (with 12 months) calendars had anything in common, events like lunar cycles and solstice are the same all around the world – and that’s where that string of mounds comes in. Both groupings are located on both sides of HWY193 just north of the intersection with HWY60 west of Muscoda.
