2021 Map of Lone Rock SW

About this map

Carson Sink dominates the arid interior of Churchill County, representing the terminus of the Carson River where water traditionally evaporates in the high desert sun. This 2021 topographic survey focuses on the vast, flat expanse of the playa, a landscape defined by its subtle elevation changes and the legacy of ancient Lake Lahontan. The grid of the Public Land Survey System, including t23n r31e and t23n r32e, provides the only structural markers across this largely featureless terrain. For researchers and geologists, the map documents the modern footprint of one of Nevada's most significant terminal drainage basins, capturing the shifting shoreline and hydrological boundaries of the sink as they existed in the early twenty-first century.
