2021 Map of Lone Rock

About this map

Carson Sink dominates this interior portion of Churchill County, a desert landscape defined by the remnants of prehistoric water systems. The map depicts a stark, arid basin where seasonal drainage patterns are marked by ephemeral features like Packard Wash, which carries water across the flats toward the sink. In the southern reach of the survey, the namesake Lone Rock stands as a solitary topographic sentinel above the surrounding alkali flats. This survey by the U.S. Geological Survey illustrates the intersection of several townships, including t24n r32e, showing a region largely devoid of permanent settlement but critical for understanding the hydrological history of the Great Basin.
