Study Area Boundary and Surficial Hydrogeologic Units for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert

This U.S. Geological Survey data release presents the study area boundary and surficial hydrogeologic units for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. The study area boundary delineates a spatial extent defined to include the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. Within this boundary, surficial hydrogeologic units polygons represent two hydrogeologic classes, subdivided into nine hydrogeologic units. Each unit includes associated geologic information and estimated ranges of horizontal hydraulic conductivity.
