Original 1893 U.S. Coast and Geodetic Survey chart showing the Appomattox River from City Point (modern-day Hopewell) to Petersburg, Virginia. Published under T.C. Mendenhall, this chart features hydrographic and topographic data compiled between 1853 and 1892. Produced at a scale of 1:20,000, it includes soundings in feet at mean low water, elevation curves, and detailed renderings of riverbanks, buoys, and town plans—including a partial street grid of historic Petersburg.
