2013 Map of Trio
USGS Topo · Published 2013About this map
Trio serves as the central hub of this Uvalde County landscape, where the road network converges amidst a series of deep drainages and limestone uplands. The drainage pattern is dominated by the Blanco Cr and Little Blanco Cr systems, which cut southward toward their confluence. Notable topographic landmarks such as Ringtail Mtn and Sinks Hill define the horizon, while the eastern edge of the quadrangle captures the winding course of the Sabinal River.
