The Bone-Bearing Pliocene Coso Formation, California

Coso adventurers stand ready to explore exposures of the 6.0 to 3.0 million year-old Pliocene Coso Formation old. Here, the Coso produces algal stromatolites (precipitated by blue-green algae), palynological grains (pollens from conifers and angiosperms), and occasional profuse ostracods. View is westward to the eastern slopes of the Sierra Nevada. Original photograph snapped with a Minolta 35mm camera; this image was created by photographing that original picture with a Nikon CoolPix 995 digital camera.
