Dakota sandstone.
The upper member of the formation consists of similar sandstones, usually not so thick, less massive, and with less conglomerate. Between the sandstone members is a series of interbedded dark shales and buff sandstones, with here and there thin beds of coal. The thickness of the whole "Dakota" series is about 200 feet.
