Apr 24, 2023 · About 100 million years ago, the sea reached the Mesa Verde area and deposit ed the Dakota Sandstone. Initi ally, sand was deposited in a very shallow area of the sea near the beach. The sand was compacted and cemented into sandstone. These rocks form the erosion resistant base of the Montezuma Valley below Mesa Verde, around the city of Cortez. Throughout Denver region and for much of distance along east base of Rocky Mountains in Colorado, the Jura is essentially a formation of fresh-water marls, of average thickness of 200+/- feet.

Permeability of Dakota aquifer sandstones in Kansas and in the Denver basin is a function of depositional environment, diagenesis, and postdiagenetic history (Figure 44). Sandstones closer to the axis of the Denver basin were deposited in marine and coastal plain environments and are clayey, tightly cemented, and less permeable.

After 38 years of groundwater pumping in a confined Dakota sandstone aquifer, a total volume of 110 million cubic meters has been produced. Over that period, the hydraulic head declined about 100 meters. The specific storage due to the expansion of water alone is found to be 9 x 10-7 m-1. The aquifer spans a horizontal area of about 109 m2.
