Tristates serves as a critical junction where New York, New Jersey, and Pennsylvania converge at the confluence of the Delaware River and Neversink River. This mid-century survey illustrates the complex geography of the Tri-State area, dominated by the ridge of High Point State Park and its landmark High Point monument. The settlement patterns reflect a landscape defined by water and topography, with the Erie RR following the river valleys and small hamlets like Colesville and Duttonville scattered along the lower elevations. Higher elevations remain largely undeveloped, characterized by numerous water bodies such as Lake Marcia and Steeny Kill Lake. The presence of the Matamoras Airport and the Life Magazine Camp indicates the region's mid-century role as both a transportation hub and a destination for recreation and institutional camps, while localized industry is represented by the Rock Quarry near Clove Brook.
