Rogers Spring and others in the “North Shore Complex”comprise one of the discharge areas for the carbonate-rock aquifer system of eastern Nevada and western Utah. The source of the water to this and these other regional springs is not known. One theory, however, suggests that recharge occurs in the Morman Mountains, located some 30 miles to the north. As ground water flows south through the carbonate rocks, it encounters the Rogers Spring Fault which has juxtaposed sedimentary rocks and evaporite deposits of the Muddy Creek and Horse Spring formations. Here the lesser transmissivity of these finer-grained, more-recent rocks, along with sufficient hydraulic head, forces the water to emerge at surface.
