A group of cinder cones near Pleistocene Burney Mountain volcano, including Twin Buttes to the SE, is part of an area of extensive Quaternary volcanism north of the Lassen volcanic center. Twin Buttes at one time was considered to be Holocene (Miller, 1989), late Pleistocene, or early Holocene, but Clynne et al. (2012) assigned an age of 10,000-15,000 years to Twin Buttes. Blocky, partially unvegetated lava flows extend to the north from North and South Twin Buttes, which are located at the SE foot of the Burney Mountain lava dome complex.
