1968 Map of Brown Summit SW

About this map

Big Sand Springs Valley defines the topography of this high-desert region in Nye County, as documented by the U.S. Geological Survey through aerial photography and field checks. The expansive valley floor is characterized by the prominent drainage of Sand Springs Wash, which snakes northward through the alluvial terrain. The map reflects a landscape of stark geological features and vast open spaces, captured during a 1967 survey and later updated with photorevisions in the early 1980s. This specific survey provides a detailed look at the water-carved channels and elevation gradients of this corner of Nevada before later modern developments, serving as a primary source for understanding the hydrologic patterns and natural landforms of the Great Basin.
