1905 Map of Slide Mountain

About this map

Ashokan Reservoir dominates the northeastern corner of this Catskills region, which was surveyed shortly before the 1912 updates by the Board of Water Supply. The terrain is defined by the high peaks of Slide Mountain and Peekamoose Mountain, shielding narrow valleys where small settlements like Sundown and Lackawack were established. The map documents the early 20th-century transportation network, including the Gulf Road and the Ontario and Western RR winding through the southeastern corridor near Kerhonkson. Diverse water systems including Rondout Creek and the West Branch Neversink Creek converge here, illustrating the complex hydrology that made the area vital for New York's growing water needs. Scattered hamlets like Samsonville and Wawarsing serve as historical anchors in a landscape transitioning between remote wilderness and managed resource.
