Earthen Mounds are found all along the Mississippi River from Minnesota to Louisiana and East of the Mississippi from New Hampshire to Florida.  Extensive trade networks existed in Mississippi that imported copper, galena, mica and greenstone from far distances connecting all these sites in a expansive distribution network of natural resources.

Mounds shaped like animals are called effigy mounds.  In Iowa's Effigy Mounds National Park there are over 200 Mounds, several shaped like bears and birds.  From 700 AD to 1250 AD Effigy Mounds were constructed in Iowa, Wisconsin, Minnesota and Illinois.  

Mound Building is truly ancient and prolific spanning many cultures and continents. It is clear the ancient cultures in America are comparable to the greatest civilizations in history. Where the mound building culture began is difficult to decipher, many are no longer standing.  Several of the the mounds in America have been leveled for farm land and modern urban expansion.
