Archeological Investigations in Nicholson, Corbin, and Weakley Hollows.Central District, Shenandoah National Park by Audrey J. Horning, Colonial Williamsburg Foundation.Three hollows in the central district of the park—Corbin, Nicholson and Weakley hollows—are presently under examination in the National Park Service-sponsored study designed to inventory the material remains of the park's human past. Located on the eastern slopes of the Blue Ridge, in the shadow of Old Rag Mountain in Madison County, Virginia, the three hollows were home to approximately 460 persons when Shenandoah National Park was created in the 1930s, having been continuously occupied by settlers of European descent since the late eighteenth century. Eighty-eight sites have been located in the three hollows, which cover approximately 2500 acres. The archaeological evidence from these hollows, the most apparently uniform of Blue Ridge communities, tells a story of adaptation, alteration, cultural retention, and individual agency throughout the period of settlement.
