Buried feature in the Sacramento Valley, about seven miles southwest of the City of Sacramento. Located on 3D seismic (Blake, 1998). The Cowell crater is located 13-16 km southwest of the City of Sacramento, pretty much centered in Sec. 24, T8N-R3E, Mt. Diablo Base and Meridian (R. Blake, 2007 - pers. comm.). The impact occured on ancestral Sacramento River flood plain during Miocene time about 25 to 30 million years ago (Blake, 1998). Coordinates derrived from topographic map.
