The westernmost set of metamorphic mountains in Georgia, the Cohuttas reach east from the Carters Dam Fault to the Murphy marble belt, and south from Tennessee to Carters Lake. Although not as high as northeast Georgia mountains, they sport some of the state's best hiking trails. Most of these mountains are set aside as the Cohutta Wilderness, conterminous with the Big Frog Wilderness in Tennessee.
Most Cohuttas rock comprises metamorphosed sediments, evidently deposited at the seaward edge of Proto-North America's continental shelf. Some rock appears to date from breakup of the supercontinent that preceded Pangea! At the leading edge of a slab of metamorphic rock pushed westward onto the continental shelf, Cohutta rocks are a scrambled mess of metagraywacke, schist, quartzite, and igneous fragments. Ugly rocks, lovely mountains.
