1986 Map of Tonkin Summit

USGS Topo · Published 1986

About this map

The Simpson Park Mountains and Roberts Mountains dominate this high-desert landscape in central Nevada, partitioned by the wide floor of Denay Valley. This mid-1980s provisional survey shows a region defined by its water sources and mining exploration, with numerous unnamed Prospects dotting the slopes of Rooster Canyon and Pat Canyon. Scattered ranching and transit points like Indian Ranch and the small settlement of Tonkin provide human anchor points in the vast basin-and-range topography.
