Pre-Monterey subcrop and structure contour maps, western San Luis Obispo and Santa Barbara Counties, south-central California
Pre-Monterey (Miocene) subcrop and structure contour maps have been compiled from existing maps and well-hole data to depict the distribution of rocks that lie beneath the Monterey Formation and on which Tertiary rocks were deposited. These maps indicate the general topography of the sea floor when the Monterey Formation was deposited.
