About this map

Gunnison National Forest dominates this mid-1960s landscape, centered on the high plateau of Flat Top. The terrain is defined by a sophisticated network of high-altitude water management, where the Gunnison Highline Canal and several private irrigation works like Teachout Ditch, May Bohm Ditch, and Lone Pine Ditch divert flows from the principal drainages. These engineered waterways reflect the critical role of water rights and ranching infrastructure in the Gunnison Basin.

Transport history is visible along the banks of Ohio Creek, where an Old Railroad Grade follows the valley floor, marking the path of former narrow-gauge operations that once served the region's extractive industries. Small-scale resource extraction is further evidenced by a lone Mine in the northern reaches near Willow Creek. The map also precisely locates the New Mexico Principal Meridian, a fundamental line for the regional land surveys that defined property and range boundaries in this part of Colorado.
