Indian Mound Park

Indian Mound Park, also known as Shell Mound Park or Indian Shell Mound Park, is a park and bird refuge located on the northern shore of Dauphin Island, a barrier island of Mobile County, Alabama in the United States. In addition to the many birds which visit, a wide variety of botanical species contribute to the natural offerings. The site is historically significant due to the presence of prehistoric Indian shell middens, mounds composed of discarded oyster shells. The park was added to the National Register of Historic Places on August 14, 1973. It is administered by the Alabama Department of Conservation and Natural Resources.
