Canyon City and John Day anchor this portion of the high desert, where the John Day River valley meets the steep timbered slopes of the southern Grant County mountains. The landscape is defined by the legacy of resource management and aviation, featuring the Grant County-Regional Airport and industrial water infrastructure like the San Juan Log Ponds, Luce Ditch, and the Trowbridge Ditch. Settlement patterns here follow the water, with neighborhoods clustered along Canyon Cr and the riverbanks.
