geophotographic re-exploration of the fortieth parallel, 2014-15

A re-documentation of the prepatory journey of the 19th century USGS land survey team, enlisted to create the  "Report of the Geological Exploration of the Fortieth Parallel" (1867 - 69), from the Bay Area to Nevada City, CA. This leg of the journey was uniquely unproductive and the  data gathered was ommitted from the official report created for the US War Department.
