About this map

Ashokan Reservoir dominates the northeastern corner of this Catskills landscape, reflecting the massive civil engineering projects undertaken to secure water for New York City. The terrain is characterized by the high peaks of the Shandaken and Denning ranges, including the towering Slide Mtn and Peekamoose Mtn. These elevations define the drainage basins for the Neversink Creek and Rondout Creek, which carve deep valleys through the wilderness.

Settlement patterns follow these watercourses, with isolated outposts like Peekamoose Lodge and Sundown providing mountain access. To the south, the Ontario and Western RR runs through the Wawarsing area, connecting riverside communities like Kerhonkson and Wawarsing to the broader regional economy. The inclusion of the Military Line and early 20th-century reservoir updates makes this a crucial document for understanding the transition from a remote timber and tannery region to a managed watershed.
