Geophysical investigations were undertaken in east-central Nevada and west-central Utah as part of a larger effort to conduct a water-resources study of the basin-fill and carbonate-rock aquifers as mandated by the Lincoln County Conservation, Recreation, and Development Act of 2004. We combined new gravity data with existing aeromagnetic, drill-hole, and geologic data to help determine basin geometry, infer structural features, estimate depth to pre-Cenozoic basement rocks, and further constrain the horizontal extents of exposed and buried plutons.
