Hudson River navigation and the military significance of the Highlands define this early 20th-century survey. The terrain is marked by steep ridges and tactical landmarks like West Point and Constitution Island, which sit across from Garrison. Industrial and infrastructure development is evident in the Mahopac Mines to the east and the presence of the Central New England RR. The map captures a moment before the modern parkway system transformed the valley, showing the traditional ferry and rail-oriented layout of river towns like Cold Spring, Peekskill, and Dutchess Junction. Large water projects are visible through the Muscoot Reservoir and New Croton Reservoir, reflecting the region's role in supplying the metropolitan area. Notable landmarks such as Bear Mountain Bridge and Anthonys Nose anchor the southern reach of the Highlands.
