2011 Map of McCarthy Ridge

About this map

McCarthy Ridge and its surrounding high desert landscape in Malheur County are defined by a critical network of water management and historic transit corridors. Small reservoirs, such as McCarthy Ridge Reservoir, Tub Mountain Reservoir, and West Tub Mountain Reservoir, indicate the importance of water storage in this arid region of Eastern Oregon. The map tracks numerous named water sources, including Beirman Spring, McDowell Spring, and Lower Mud Spring, which likely served as vital stopovers for livestock and early travelers. The presence of the Old Oregon Trl passing through the eastern portion of the quadrangle highlights the area's significance as a passage for westward migration. This 2011 survey also details local infrastructure like Moores Hollow Rd and Willow Springs Camp, providing a clear view of how these remote lands are utilized for ranching and recreation.
