1954 Map of Sonora

About this map

The Divide Country of the Edwards Plateau dominates this mid-century survey, illustrating a landscape defined by deep draws and canyons that channel water toward the Pecos River and the various forks of the Llano and Devils rivers. The transition from the rugged canyonlands in the west to the higher ranching country of Sutton County is evident, with Sonora and Ozona serving as the primary commercial hubs along the developing U.S. 290 corridor.
