1985 Map of Mail Summit

About this map

The Mount Irish Range dominates this mid-1980s landscape, illustrating a high-desert environment defined by steep relief and scarce water sources. This portion of Lincoln County is characterized by the broad expanse of Coal Valley to the north, giving way to the complex topography surrounding Mail Summit. Evidence of historical exploration and resource extraction is visible through the presence of Mine Shafts located near the head of Silver Canyon. These features, along with isolated water points like Henry Spring and Springer Spring, suggest a history of prospecting and ranching in a territory where movement was largely dictated by the natural corridors of the range. The map provides a precise look at the unimproved roads and trails that served as the primary infrastructure for this high-elevation basin-and-range country.
