About this map

Cibolo Creek and the Frio River converge in this corner of La Salle County, defining a landscape marked by ranching infrastructure and early industrial marks. The settlement of Los Angeles sits at the western edge, linked to the smaller outpost of Dull by a straight thoroughfare that runs parallel to an Old Railroad Grade. This decommissioned rail line provides a clear look at the transportation history of South Texas before the modernization of the local road network.

Water management is central to the land use here, shown through a dense network of specialized reservoirs such as TCU Tank, Quintana Tank, and Salt Well Tank. The presence of several Oil Wells and a Pipeline cutting through Dull Flats indicates the growing petroleum interest of the late 1960s, while terrain features like McGraw Lake and Cayman Slough indicate the natural drainage patterns of the Brush Country.
