The 61.55 acre Crystal River Archaeological Zone (8CL1) is located on the Crystal River within the Crystal River Preserve State Park. It is a National Historic Landmark and contains at least six mounds. This important Native American occupation site is located on the Central Gulf Coast of the Florida Peninsula, about 92 miles north of the mouth of Tampa Bay and 20 miles south of the mouth of the Suwannee River. It is possible to canoe on the Suwannee River to the Okefenokee Swamp in Georgia then on the St. Marys River to the Atlantic Ocean. This was a major trade route in pre-European times. The entrance to the park is about two miles northwest of the town of Chrystal River, off of US 19/98.
