USGS Topo · Published 1976About this map
John Day and Canyon City anchor this 1970s survey of central Grant County, revealing a landscape deeply marked by its mining heritage. The valley floor along the John Day River is dominated by extensive Dredge Tailings, evidence of industrial-scale gold recovery that reshaped the river's course. To the south, the historical significance of the area is further evidenced by the Old Humboldt Diggings and Marysville Placer, alongside smaller operations like the Potato Patch Mine.
