Harmony is situated in the high plateau country of Sherman County, where the landscape is defined by deep, winding drainage systems. The most dramatic geographical feature is the John Day River, which snakes through the southeast corner, forming a sharp meander known as The Gooseneck and passing Horseshoe Falls. This river serves as the natural boundary between Sherman and Gilliam counties, a line that traces the steep canyon floor. On the plateau above, the settlement pattern is sparse, tied to the network of local routes like Hay Canyon Rd and Ruggles Grade. Water sources are critical in this dry environment, evidenced by named sites such as Kenny Spring and Willow Spring. The terrain is carved by a succession of significant canyons, including Cottonwood Canyon, Bruckert Canyon, and Little Ferry Canyon, which break the upland plains and lead down toward the river basin.
