Trinity County
The Trinity River is a north-state benchmark because it combines historic placer-gold country with Klamath Mountains metamorphic and ultramafic source rocks. USGS mapping documents the basin's complex bedrock setting, while the RockHoundR candidate minerals add chalcedony, jasper, jade, and petrified wood to the river's placer-gold identity.
