The Dakota Sandstone records the alternating rise (shale) and fall (sandstones) of sea level as the shoreline moved back and forth across the area~ 98 to 100 million years ago. Gradual, long-term rise in sea level deposited rocks of the Graneros Shale of the Mancos Group, a mud deposited on a shallow ocean floor about 98 million years ago.The water table in North Dakota ranges between 15 and 50 feet deep, or 100 feet in upland areas. Fully wet areas are recognized in drill cores by unoxidized dark material. The lignite and sandstone of the Fort Union Group in the west is the top groundwater unit and a common source of water for farms and ranches.
Sandstone predominates in the upper 10 to 20 feet.
