Dayville serves as the focal point of this Grant County survey, situated at the confluence of the John Day River and its south fork. The map records a landscape defined by ranching and resource management, including an aviation Landing Strip and a Flume south of town. Notable for genealogists is the Dayville Cem, while land use is clearly divided between private holdings and federal protections like the Ochoco National Forest and the John Day Fossil Beds Nat Mon (Sheep Rock Unit).
