1993 Map of Callao

USGS Topo · Published 1996

About this map

Callao anchors this map in Snake Valley, a remote desert landscape where water sources dictated the path of westward expansion. The settlement’s history as a critical watering hole is evident in the numerous hydrologic features such as Big Spring, Redden Springs, and the Swimming Hole, along with various flowing wells. This vital water supply supported the operations of the Pony Express Overland Stage Route, which cuts across the terrain alongside the modern Pony Express Road.
