15. INDIAN MOUNDS.

There are about 30 mounds in this area, 7 of which are large, ranging in height from 5 to 15 feet. With one exception, all are flat-topped platform mounds. The one having a different form is an oval-shaped burial mound.

The mounds were excavated in 1934 under the direction of the Smithsonian Institution. Quantities of broken pottery, bone implements, stone tools, and weapons were removed. Twelve skeletons were found in the oval burial mound.

The effigy pipe, now on display at park headquarters, was removed from the burial mound in 1899 under the direction of the Park Commission.
