Twin Buttes are part of a group of cinder cones near Pleistocene Burney Mountain volcano. North Twin Butte (left) and South Twin Butte (right) rise above flat-lying forests and meadows SE of Burney Mountain. The cones are part of an area of extensive Quaternary volcanism north of the Lassen volcanic field. Twin Buttes and associated lava flows are of late-Pleistocene or early Holocene age.
