Galena serves as the focal point of this late-1960s survey, situated where the Galena River cuts through the high bluffs of northwestern Illinois. The landscape reveals a legacy of extraction, with numerous workings like the Appleton Mine and Flower Mine dotting the terrain near Council Hill and Vinegar Hill. The Fourth Principal Meridian runs through the center of the sheet, providing a primary surveying baseline for the region's agricultural and mining tracts.
