The John Day River snakes through the high desert border of Sherman and Gilliam Counties, carving deep relief into the plateaus of North Central Oregon. This landscape is defined by its steep access points, where engineered routes like Ruggles Grade and Taylor Grade descend toward the water. The river passage is marked by Big Eddy, a notable water feature near the historic crossing at Cottonwood Bridge.
