This area is not at the mineral springs and resort. It is five miles west of the mineral springs, on modern-day Georgia Highway 225, a mile or so south of the Tennessee state line.
Link to 1863-1865 post with map (drafted 1863-1864; published 1865) showing the area south of the Conasauga River, but not designating Cohutta Springs P.O. The relevant area on this map is the road running from Spring Place directly north toward Benton Pike, just where it intersects a road that runs southeast toward Ellijay. The place name of Cohutta Springs (where the post office was located from 1836 until at least 1865) does not appear on the map. However, east of that area, on a road running parallel to the S.P. and Cleveland Road, is "Cohutta Springs" (Cohutta Springs, east), where the resort and mineral springs would be located.

*Typically these main roads run between two towns and are named, in a broad sense, for both towns; hence, "Spring Place and Cleveland Road." Locally, the people in Cleveland or Charleston, Tennessee, would probably refer to it as "Spring Place Road," while people in Spring Place would refer to it as "Cleveland Road" or "Charleston Road."
