介绍：Thunder Valley Casino Resort is owned by the United Auburn Indian Community, a Native American tribe consisting of mostly Miwuk and Maidu Indians indigenous to the Sacramento Valley region. In the 1950s and '60s, the United States government terminated 41 California rancherias—mini-reservations, including that of the Miwok and Maidu Auburn band. As a way to lift themselves out of poverty, the members of the tribe decided to build a casino after Congress restored the tribe's federal status in 1994, allowing the tribe to acquire land under tribal sovereignty
