Western North Dakota is in the Williston Basin, an oil and gas producing area. Sedimentary rock outcropping ranges in age from the late Cretaceous Niobrara formation to late Tertiary. The eastern portion of the state is covered with several hundred feet of glacial deposits. Agates and petrified wood can be found in numerous gravel deposits throughout the state.
