The settlement of Harmony sits amidst a complex network of drainage basins and deep incisions into the Columbia Plateau, as recorded in this 2020 topographic survey. The eastern boundary of the quadrangle is defined by the winding course of the John Day River, which forms the border between Sherman Co and Gilliam Co. This area is characterized by high-relief terrain featuring numerous named canyons, including Hay Canyon and Cottonwood Canyon, and the distinctive river meander known as The Gooseneck.
