A large and rare map showing the gold country settlement of Dutch Flat, California, and the adjacent mines, crossed by Canyon Creek, Bear River, the North Fork of the American River, and the tracks of the Central Pacific Railroad, with the ribbon of the Blue Lead winding horizontally across the center. The mines and mining properties are identified, and the houses of Dutch Flat depicted. At lower left is an inset of the "Economic Geology from Government Surveys" of the larger region, with Dutch Flat at the center. The map is reproduced from the manuscript of Edward C. Uren, a local mining engineer from Nevada City, and dates to the last period of heavy commercial mining of the area, with the end of hydraulic mining there coming after 1914. Uren made numerous survey and mining maps of areas in Placer and Nevada Counties, but we are unable to locate any copies of the present work. Not in OCLC.
