1910 Map of Greenwood Lake

About this map

Greenwood Lake straddles the border of New York and New Jersey, serving as the central geographic feature for this early 20th-century landscape. The surrounding terrain is defined by industrial extraction and water management, with numerous iron operations like the Charlotteburg Mine, Parker Mine, and Cannon Mine scattered across the ridges. The eastern edge is anchored by the Sterling Mountain Railroad and the historic Sterling Furnace, reflecting the region's long-standing connection to the iron industry. To the west, the growing demands of regional infrastructure are evident in the Oak Ridge Reservoir, Canistear Reservoir, and Clinton Reservoir, which transformed the natural flow of the Pequannock River. Smaller settlements like New Milford Sta. and Ringwood Junction reveal a network of rail-dependent communities, while local landmarks such as the Maples Grange and Parker School provide essential points of reference for genealogists tracing family roots in this corner of Orange and Passaic counties.
