About this map

Mining history and irrigation infrastructure define this corner of Gunnison County, where the high-altitude landscape of Flat Top overlooks a complex network of man-made waterways. The presence of the Great Western Mine and Ohio Creek Mine in the northwest corner points to the mineral interests that historically drove development in this part of Colorado. Below these elevations, the management of water is evident through numerous named channels, including the Campbell Ditch, Teachout Ditch, and Lone Pine Ditch, which redirect flow across the terrain.

The natural drainage is centered on Ohio Creek, which is joined by tributaries from steep drainages such as Maggie Gulch and Cunningham Gulch. The southern extent of the map includes the Gunnison Highline Canal, a major piece of engineering that transformed the local valley. This 2011 survey by the U.S. Geological Survey captures a landscape where traditional resource extraction and ranching-related irrigation systems intersect with a modern rural road network, including County Rd 730 and Eagle Creek Rd.
