Red Clay State Historic Park is located in the extreme southwest corner of Bradley County
, just above the Tennessee-Georgia
state line. The park encompasses 263-acres of narrow valleys formerly used as cotton and pasture land.
There are also forested ridges that average 200 feet or more above the valley floor. The site contains a natural landmark, the Blue Hole Spring, which arises from beneath a limestone ledge to form a deep pool that flows into Mill Creek
, a tributary of the Conasauga and Coosa River system. The spring was used by the Cherokee for their water supply during council meetings.
