Wallpack Ridge (or Walpack Ridge) is a mountain located in the Ridge and Valley Appalachians physiographic province in Sussex County in northwestern New Jersey. Oriented northeast to southwest, Wallpack Ridge spans from Montague Township south of Port Jervis, New York to the Walpack Bend in the Delaware River near Flatbrookville in Walpack Township. It is a narrow ridge ranging between to in width, and its highest elevation reaches above sea level.〔Witte, Ron W., and Monteverde Don H. "Karst in the Delaware Water Gap National Recreation Area" from (Unearthing New Jersey ) (Newsletter) Vol. 2 No. 1 Winter 2006. (Trenton: New Jersey Geological Survey, Department of Environmental Protection, 2006).〕 The ridge separates the Wallpack Valley from the valley of the Delaware River (also known as the Minisink or Minisink Valley), and contains the watershed of the Flat Brook and its main tributaries Big Flat Brook and Little Flat Brook.〔Witte, Ron W., and Monteverde Don H. ("Geological History of New Jersey's Ridge and Valley Physiographic Province" ) (Trenton, New Jersey: New Jersey Geological and Water Survey. New Jersey Department of Environmental Protection, 2012).〕 A controversial project to build a hydroelectric dam and reservoir on the Delaware River in the 1950s and 1960s led to government's seizure of land in northwestern New Jersey and northeastern Pennsylvania under the authority of the U.S. Army Corps of Engineers. The construction of the dam would have created a lake reservoir that would have flooded the Walpack Valley. For political and geological reasons, the dam project was deauthorized and the land transferred to the management of the National Park Service for the establishment of a National Recreation Area.〔Feiveson, Harold; Sinden, Frank; and Socolow, Robert. ''Boundaries of Analysis: an Inquiry Into the Tocks Island Dam Controversy.'' (1976); Albert, Richard C. ''Damming the Delaware: The Rise and Fall of Tocks Island Dam'' (State College, Pennsylvania: Pennsylvania State University Press, 1987).〕 Currently, Wallpack Ridge is located in the Delaware Water Gap National Recreation Area that was established by the National Park Service in 1978. ==See also== * Brau Kettle * Geology of New Jersey * Old Mine Road * Van Campen's Inn 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wallpack Ridge」の詳細全文を読む スポンサード リンク
