1965 Map of Greeley

About this map

The Cache la Poudre River flows from the high peaks of Roosevelt National Forest down into the intensive agricultural plains of the South Platte River valley. This mid-century survey captures the region during a period of complex water management and rail-driven commerce, as seen in the extensive network of irrigation canals and reservoirs like Horsetooth Reservoir and Milton Reservoir. The eastern plains are dotted with smaller agricultural hubs such as Keenesburg and Wiggins, while the western portion is dominated by the granite massifs of Rocky Mountain National Park, including Longs Peak. Major transportation arteries, including the Union Pacific Railroad and Chicago Burlington and Quincy Railroad, link the established settlements of Greeley and Fort Lupton to the broader regional economy, illustrating the transition from wilderness to a highly developed pastoral landscape.
