The Greenville Rancheria is currently located in the Indian Valley at the 3,500 foot level in the Sierra Nevada Mountains of Northern California. The Rancheria lies about three miles east of Greenville, California, which has a population of 2000. The tribal government offices have historically been located in Redding, Red Bluff and Greenville, and are currently in Greenville. The Rancheria runs a medical and dental facility in Greenville and Red Bluff to serve tribal and non tribal persons.
The native inhabitants of Plumas, Tehama and surrounding counties, occupied the Feather River region, Sacramento region and its many tributaries. The terrain is mostly forested ridges dotted with high lakes and green valleys. Big Meadows is now Lake Almanor. Indian Valley, Genesee, American and Sierra valleys are now occupied by Plumas County settlements, but once were occupied solely by the Tribe. The areas to the east, namely Mohawk and Sierra valleys were claimed for hunting grounds, containing few, if any, permanent villages due to heavy winter snow. During snow season, the Tribe moved west to Paynes Creek and to the Sacramento River Region.
