The settlement of Knippa serves as the focal point for this survey of eastern Uvalde County, situated where the southern plains meet the rising Edwards Plateau. This area is defined by its complex drainage network, most notably the seasonal courses of the Dry Frio River and the Frio River, which carve winding paths through the landscape. The geography is punctuated by several prominent elevations that rise abruptly from the surrounding flats, including Blue Mtn, Black Mtn, and Big Mtn. These peaks likely owe their prominence to the volcanic activity suggested by the name Traprock Hill located just south of the town center. Local infrastructure is anchored by the corridor of US Highway 90 and a web of county roads that navigate between significant landmarks like Taylor Slough and Long Hollow. The map provides a clear picture of how water availability and terrain have shaped the agricultural and transport patterns in this part of Texas.
