Ocmulgee National Monument The National Monument preserves a continuous record of human life in the Southeast from the earliest times to the present. From Ice-Age hunters to the Muscogee (Creek) people of historic times, there is evidence here of 12,000 years of human habitation. The Monument today consists of two units separated by two miles of riverine wetlands along the Ocmulgee River. The Main Unit is adjacent to the city of Macon, an urban area with a population of 118,000. The isolated Lamar Mounds and Village Unit can be visited by special permit. Designated a National Monument on December 23, 1936.
