Mason and Dixon Survey Terminal Point

Mason and Dixon Survey Terminal Point is a historic marker located near Core, West Virginia and Mount Morris, Pennsylvania, United States. Located on the boundary between Monongalia County, West Virginia and Greene County, Pennsylvania,^[1] it identifies the terminal station established by Charles Mason and Jeremiah Dixon on Brown's Hill. The surveyors took astronomical observations and on October 19, 1767, finally establishing the point on Brown's Hill.^[2] The reason behind Mason & Dixon stopping here and not at the western most point of Pennsylvania is because the Native Americans told the surveyors they would not proceed one step further. This was due in part to them just crossing the Catawba Trail.^[3] In 1883 Cephas H. Sinclair placed the current stone atop Brown's Hill in the mound left by Charles Mason and Jeremiah Dixon in 1767. This stone marks the westernmost point reached by Mason and Dixon in delineating the common boundaries of Pennsylvania, Maryland, Delaware, and Virginia (now West Virginia), and known as the Mason–Dixon line.^[4]
