About this map

The Union Pacific railroad corridor serves as the primary spine for this portion of Placer County, connecting a string of historical settlements including Colfax, Weimar, Heather Glen, and Applegate. The terrain is defined by deep incisions like Robbers Ravine and Slaughter Ravine, which lead toward the protected North Fork American Wild and Scenic River. This landscape reflects the complex intersection of early California transportation routes and challenging topography, where names like Cape Horn and Iowa Hill Divide speak to the region's pioneering history.

Local landmarks such as the Colfax Cem and the Weimar Sanitorium Cem provide specific points of interest for genealogists. The map also documents named flats and hills that were central to the local geography, from John Brown Flat to Indian Knoll. Much of the eastern portion of the quadrangle remains dominated by natural features like Shirttail Canyon and Devils Canyon, illustrating the sharp transition from rail-town civilization to the wilder canyons of the American River system.
