Kettleman Hills

The Kettleman Hills ACEC is located just west of Kettleman City in Kings County. The ACEC encompasses 6,730 acres of Federal surface and subsurface and 3,765 acres of Federal minerals.

Rock formations exposed in the Kettleman Hills range in age from Pleistocene to Eocene. In these formations invertebrate marine fossils are abundant. However, marine and terrestrial vertebrate fossils are also found. The fossils identified from the area include mastodon, beaver, peccary, horse, camel, deer, sea lion, seal, porpoise, shale, turtle, shark and cormorant. The area is also habitat for four Federally listed species: the San Joaquin kit fox, blunt-nosed leopard lizard, San Joaquin woolly-threads, and Hoover's woolly-star. A wide variety of raptor species also use the area for nesting, foraging and wintering.

Oil was first successfully produced here in 1928, and has since produced over 440 million barrels of oil from Eocene, Oligocene, and Miocene reservoirs. There has also been some mining of clay and gypsite from the area, but not from the fossiliferous sedimentary rocks.

Numerous existing authorizations, including rights-of-way, oil and gas leases, and grazing leases occur here. The existing authorizations are primarily oil field related.

The ACEC meets the relevance and importance criteria as warranted by the significant paleontological, biological, and oil resource values .

Objective      Manage to provide protection to significant paleontological resources and federally listed plant and animal species and allow continued oil exploration and development.

Management Prescriptions

This ACEC is open for the leasing of oil, gas, and geothermal resources subject to the following stipulations: LSU - Protected Species and LSU - Raptors.

The ACEC is available for livestock grazing and is currently allotted and grazing will continue to be authorized.

Support Actions

Cooperatively manage the Kettlemen Hills ACEC with adjoining Panoche/Coalinga ACEC in the Hollister Resource Area.
