Summary:

[Named for Bickmore Canyon, San Benito Co, CA north of Pinnacles National Monument]. At least 6,000 ft of upper Miocene shales with some interbedded sands were deposited in trough portion of Bitterwater Basin. This entire section becomes sandy to northwest where its equivalent in outcrop is Bickmore Canyon arkose east of Pinnacles. Bickmore Canyon arkose consists of poorly sorted variety of rock types that suggest nonmarine deposition. To east of Bitterwater Basin, narrow fault block has about 2,000 ft of unit resting on older rocks. Arkose here includes O'Connor producing sand of Bitterwater field. Is late Miocene age.
