2013 Map of Vinson Wash

About this map

Vinson Wash cuts through this high-desert landscape in Owyhee County, illustrating the drainage patterns that define the terrain south of the Snake River. The presence of the Grand View-Irrigation District Canal in the northeast corner signals the vital role of water management in this arid region, providing a stark contrast between the natural arroyo systems and man-made infrastructure. This survey captures a transition from the level expanse of Twentymile Flat to the more dissected country marked by Poison Gulch and McKeeth Wash. While infrastructure is minimal, Riverside Rd provides one of the few formal access points through the township sections. For researchers, the map provides a clear record of the hydrography and public land survey system lines, including the corners of T5S and T6S, during the early 21st century.
