Mount Vernon serves as the focal point of this Grant County survey, where the John Day River winds through a landscape defined by ranching and early industrial water management. The irrigation network is particularly dense here, featuring the Panama Ditch, Enterprise Ditch, and Laycock Long Ditch, which redirect water across the valley floor to support local agriculture. North of the river, the terrain rises into the Malhuer National Forest, punctuated by prominent landmarks such as Grouse Mtn and Gordon Butte.
