This is a highly detailed early land survey map of Southern and Central California from Los Angeles to San Francisco. The work is a culmination of two years worth of surveying potential routes for a Pacific Railroad that would link all major cities and settlements along the west coast with transcontinental lines extending eastward to the Mississippi River and beyond.
