2010 Map of Trio

About this map

Blanco Creek and the Sabinal River define the drainage patterns of this South Texas landscape, where the small community of Trio sits at a junction of rural roads. The terrain is characterized by a series of deep draws and high points, including Ringtail Mountain and Sinks Hill, interspersed with named depressions such as Catclaw Hollow and Turkey Hollow. This 2010 survey illustrates the remote character of the region, where water sources like Reiner Springs and the seasonal flows of Nolton Creek were historically vital for ranching operations. The presence of Long Crossing suggests a longstanding point of transit across Little Blanco Creek, connecting isolated homesteads to the broader network of county roads like Co RD 336 and Farm Rd 30.
