Sweetwater: Barite & Fluorite Rockhounding in Monroe County, Tennessee

Updated July 2026

The Sweetwater district is a Mississippi Valley-type system in the Ordovician Knox Group that was mined for residual barite and carries fluorite, sphalerite, galena, and pyrite at depth. It is one of East Tennessee's documented barite-fluorite occurrences, spanning parts of Monroe, McMinn, and Loudon counties. Weathered barite and fluorite still turn up in the residual clays and cuts across the district. Reported finds include barite, fluorite, sphalerite.
