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.
