High above the Mississippi, earthen mounds in the shape of birds, bears, and simple cones mark the once-flourishing Woodland Culture of the Upper Mississippi River Valley. From 500 B.C. to A.D. 1300, Eastern Woodland Indians, who were hunters and gatherers, lived in this area. They collected wild rice, nuts, fruits, berries, and freshwater mussels, and their prey included deer, bear, and bison. Like other Indians of their age, these prehistoric people also built distinctive burial mounds. While many of the
mounds have been lost, northeastern Iowa's Effigy Mounds National
Monument, proclaimed in 1949, preserves 206 known prehistoric mounds. 
ŠNational Park Service
At Effigy Mounds National Monument, visit more than 200 prehistoric burial mounds.
The mounds do contain burials, as well as artifacts, including copper beads, chipped blades, and stone and shell ornaments, indicating that the Eastern Woodland culture was part of an extensive trade network.
In 1881, however, Theodore H. Lewis and Alfred J. Hill began an ambitious survey of the mound groups of the Mississippi River Valley. Their surveys produced excellent maps of the mounds, several of which, such as the Marching Bear Group, are now part of the monument.
