The rugged Blue Mountain foothills of Umatilla County are defined by a complex drainage system that feeds McKay Creek and Bassey Creek. This landscape is characterized by prominent high points such as Storm Mtn, Baldy Ridge, and Johnson Ridge, which rise above a series of deep cuts including Gibson Canyon and Coyote Canyon. The presence of several named water sources, such as Mathis Spring, Elder Spring, and Marlin Spring, suggests the importance of reliable water in this high-elevation terrain, which serves as a critical headwaters area for the region.
