Where are mounds found?
In a general sense, Indian mounds were built throughout what is now the United States. However, the highest concentration of effigy mounds can be found in the Upper Midwest. While some effigies can be found in southeastern Minnesota, northeastern Iowa, and northern Illinois, the majority of effigy mounds were built in southern Wisconsin. Archaeological research indicates that mounds are not spread over the landscape in a uniform distribution, but rather there are clusters of mounds and mound groups. Clusters, sometimes referred to as “Super Clusters,” are found in the Madison area, the Muscoda area, and the Prairie du Chien area. Mounds are typically found situated on bluffs, ridges, bottom lands, and shorelines near resource-rich areas that were able to support temporary gatherings of large groups of people. Some mounds are found near important natural features such as islands, marshes, springs, and caves.
