2012 Map of Caverns of Sonora

About this map

Valliant Ranch and Locklin Ranch occupy this segment of the Edwards Plateau in Sutton County, where the landscape is defined by vast rangelands and seasonal drainage patterns. The 2012 survey illustrates a region largely partitioned into large family holdings, connected by a network of private roads like Private Road 4470 and Private Road 1125. Major transit is limited to the northern edge along Ranch Road 1312 and Ranch Road 1989. The distribution of ranch headquarters, including Simmons Ranch and the Mayer Number Nine Ranch, reflects the enduring pastoral character of this West Texas territory. Genealogists and land historians can trace property boundaries and access routes through this rugged limestone terrain, where traditional ranching operations like the Fawcett Ranch and Ingham Ranch have persisted into the modern era.
