The Malheur River cuts a sharp path through this high desert landscape, defining the character of the Harper Valley in Malheur County. This 1990 provisional survey documents a network of water management features essential for life in the arid basin, including numerous named stock tanks and reservoirs such as the Medlin Reservoir, Chicken Creek Reservoir, and Hollow Reservoir. The small settlement of Namorf sits along the river's edge, adjacent to a Gaging Sta and the Oregon Vale route. The terrain is marked by significant features like Hog Ridge and is dissected by seasonal drainages including Corbett Creek and Squaw Creek. This map reveals the intricate reliance on springs such as Tumbleweed Spring and Shaw Spring for livestock and local use, while the presence of a Landing Strip and various canals highlights the infrastructure required to navigate and cultivate this remote canyon country.
