It is not exposed at the surface anywhere within this area,but has been reached frequently by wells, and is known to exist bothto the east and to the west, so we are sure it is spread over the wholeof the northern and central parts. The Dakota is followed by theBenton, which is largely a limestone formation consisting of beds oflimestone alternating with black shale.
