2021 Map of Rock Hill

About this map

Columbus Salt Marsh dominates the southern basin of this high-desert landscape, serving as a terminal drainage point for the surrounding uplands. The terrain transitions from the low-lying Columbia Valley into the prominent ridges of the Monte Cristo Range to the northeast and the Candelaria Hills in the southwest. A sharp administrative boundary marks the transition from Mineral County into Esmeralda County, cutting diagonally across the northern portion of the map. The isolated summit of Rock Hill rises from the valley floor, providing a central landmark between the expansive salt flats and the mountain slopes. This 2021 survey documents the stark geological character of the region, where drainage patterns from the ranges define the arid environment.
