California Valley Rancheria
It is one of the many communities of the Black Hills Indian Reservation. I have no idea what their population is. They do have a government however. Since further information about the demographics of California Valley Rancheria is not available, stats can't be included. It was originally known as Sheep Ranch Rancheria. It is located in the Sierra Nevada Mountains, near the community of Mountain Ranch. California Valley Rancheria is located within the land cession number 281. It is linked to the Reservation set aside from land cession number 281. The Reservation number is 280. However, California Valley Rancheria is really within the boundaries of the Black Hills Reservation. All of the Sierra Nevada Mountains including the foothills, are within the boundaries of the Black Hills Reservation.
