1954 Map of Lisbon Valley

USGS Topo · Published 1983

About this map

Lisbon Valley and the surrounding mesa country of San Juan County were mapped in the mid-1950s under a cooperative agreement with the Atomic Energy Commission. This specific interest in the region's geology is reflected in the numerous Prospect labels and tunnel markers scattered across the landscape, particularly near Big Indian Rock. The map illustrates a rural ranching and mining economy centered on landmarks like Patterson Ranch and Woods Ranch.
