Big Creek: Green Quartz Rockhounding in Cocke County, Tennessee

Updated July 2026

Big Creek, in the Smoky Mountain foothills near Bluffton, is one of the few Tennessee streams known for green quartz, with some water-worn crystals reaching gem quality. The color comes from mineral inclusions in quartz shed from the surrounding Precambrian metamorphic rock. The creek gravels also carry clear quartz and other resistant pebbles. Reported finds include green quartz. Below: coordinates, access notes, nearby spots, and trip-planning links.
