The Pomerado Conglomerate Formation is a geologic formation in southwestern San Diego County, California.[1][2]

It was named for exposures located along Pomerado Road, at the divide between Carroll Canyon and Poway Valley.[1]

Geology

The Pomerado Conglomerate is of the Late Eocene Epoch, and is a massive cobble conglomerate. It is lithologically identical to the local Stadium Conglomerate.[1]

It overlies the sandstone Mission Valley Formation.[1] It is the uppermost formation of the Poway Group, and has a maximum thickness of 55 metres (180 ft).[1]

Fossils

It preserves fossils dating back to the Late Eocene Epoch of the Paleogene period, during the Cenozoic Era.[3]
