The Delaware River carves a sharp, deep arc through this borderland, where New York and Pennsylvania meet at the junction of Sullivan, Orange, and Pike counties. The river valley is a designated corridor for the Upper Delaware Wild and Scenic River, reflecting its preserved character. Higher elevations are marked by ridges like Pine Knot Ridge and the dense Bushkill Swamp, showing a landscape dominated by rugged terrain and timbered tracts. Small settlements and hamlets follow the river and mountain roads, including Glen Spey and the riverside community of Pond Eddy. Genealogy and local history researchers will find several family-named landmarks and roads, such as Van Tuyl Cem and roads honoring local names like Greg Rd and Anna Rd. The eastern edge is defined by the Rio Reservoir and the Mongaup River, where the geography shifts toward hydroelectric resources.
