Coquelle Trails: Historical USGS Quadrangle Maps

These are the digitized versions of the original USGS 30-minute and 15-minute Quadrangle maps for the study area. These maps were principally used to document historical place names for the project's written references and indices, and to help confirm the time and locations of various historical roads and trails.

The maps are provided in two formats: the first is an actual scan (often with subsequent annotations) of the original map itself; and the second is an annotated version of the same map, providing an index to Coquelle Trail Historical District maps, and to the XLS and PDF files on which they are based.
