RITA BLANCA CREEK
RITA BLANCA CREEK. Rita Blanca Creek rises in two branches in Union County, New Mexico (at 36°21' N, 102°52' W), and enters Texas near Texline in northwestern Dallam County. After the branches join southeast of Texline, the stream continues its sixty-two-mile course southeast through Hartley County to join the Canadian River in northern Oldham County (at 35°34' N, 102°29' W). The creek rises in a flat to rolling, locally active dune area covered with bunch grasses and flows into a flat to rolling area with local escarpments where soils are mostly deep, fine sandy loams and vegetation consists of hardwood forest, brush, and grasses. The creek ends in an area that is flat with local shallow depressions, where water-tolerant hardwoods, conifers, and grasses cover clay loam and sandy loam soils. The stream, often known as Mustang Creek, was included in the LIT and XIT ranges and received its name from the Rita Blanca Division of the XIT. Lake Rita Blanca is on the creek just south of Dalhart.
