Historic American Engineering Record
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS) responsible for administering the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, and are archived in the Prints and Photographs Division of the Library of Congress. Historic American Buildings Survey In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive make-work program for architects, draftsmen and photographers left jobless by the Great Depression. It was supported through the Historic Sites Act of 1935. Guided by field instructions from Washington, D.C., the first HABS recorders were tasked with docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harpers Ferry, West Virginia
Harpers Ferry is a historic town in Jefferson County, West Virginia. It is located in the lower Shenandoah Valley. The population was 285 at the 2020 census. Situated at the confluence of the Potomac and Shenandoah rivers, where the U.S. states of Maryland, Virginia, and West Virginia meet, it is the easternmost town in West Virginia. During the American Civil War, it was the northernmost point of Confederate-controlled territory. An 1890 history book on the town called it "the best strategic point in the whole South." The town was formerly spelled Harper's Ferry with an apostrophe, so named because in the 18th century it was the site of a ferry service owned and operated by Robert Harper. The United States Board on Geographic Names, whose Domestic Name Committee is reluctant to include apostrophes in official place names, established the standard spelling of "Harpers Ferry" by 1891. By far, the most important event in the town's history was John Brown's raid on the Harpers F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elk Ridge (Maryland)
Elk Ridge, or Elk Mountain, is a mountain ridge of the Blue Ridge Mountains in Maryland and is the westernmost of four parallel ridges. It forms the western side of a narrow valley in which are situated the towns of Yarrowsburg and Brownsville. South Mountain is on the eastern side of this valley running roughly parallel to it.
