Umatilla National Forest dominates this landscape along the border of Walla Walla and Umatilla counties, where the high-elevation terrain is defined by the headwaters of the North Fork Walla Walla River and the South Fork Walla Walla River. The geography reveals a complex network of drainage systems, including Big Meadow Canyon and Little Meadow Canyon, alongside prominent heights like Blalock Mountain and Yellow Jacket.
