Unaka Mountains: Epidote & Quartz Rockhounding in Unicoi County, Tennessee

Updated July 2026

The Unaka Range is the type locality for unakite, the pink-and-green ornamental rock named after these mountains, an intergrowth of pink orthoclase, green epidote, and quartz weathered from the Precambrian basement. The stone turns up as float in the Nolichucky drainage and as outcrops along the higher ridges. It is one of the few Tennessee localities on public land where a hobbyist can legally surface-collect. Reported finds include epidote, quartz, unakite. Below: coordinates, access notes, nearby spots, and trip-planning links.

Geology at Unaka Mountains

This spot sits on Unicoi Formation, mapped as sandstone, arkose, and conglomerate that formed roughly 540 to 485 million years ago. Sedimentary rock like this erodes unevenly, so the most productive collecting is typically along fresh cuts, badland slopes, and active drainages.

Mapped unit: Unicoi Formation
Age: 540–485 Ma (Cambrian)
Rock types: sandstone, arkose, and conglomerate
Elevation: 2,890 ft
