A complex of pre-Columbian shell mounds on the west bank of the Apalachicola River, built by the Weeden Island and Fort Walton cultures between roughly 200 BC and 1500 AD. The largest mound in the group is over 20 feet high and 200 feet across. The site was excavated by Smithsonian archaeologist Clarence B. Moore in 1902 and remains one of the most significant Native American sites in the Florida Panhandle.
Access is limited — most of the mounds are on private land — but a small portion is open to the public via the Pierce Mounds Complex preserve. Bring mosquito repellent and reasonable footwear; the trail is unmaintained and overgrown for most of the year.
