2018 Map of Portuguese Mountain NW
USGS Topo · Published 2018About this map
Big Sand Springs Valley dominates the western portion of this high-desert landscape in Nye County, characterized by the expansive drainage system of Sand Springs Wash. The terrain transitions sharply from the alluvial flats of the valley floor into the uplifted formations of the Red Hills and the northern reaches of the Pancake Range. This 2018 survey documents a remote section of the Great Basin, where the Public Land Survey System grid overlays a landscape shaped by intermittent water flow and geological ridges. The mapping illustrates the complex topographical contours typical of this region, providing a detailed look at the drainage patterns and elevation changes across townships such as t10n r54e and t9n r53e during the early 21st century.
