About this map

The Gunnison River and Uncompahgre River define the agricultural and transit corridors of this Western Slope region, converging at the town of Delta. Here, the irrigated valley floor supports rural crossroads like Pea Green Corner and Hookers Corner, contrasting sharply with the massive uplift of the Uncompahgre Plateau and Grand Mesa. The Denver & Rio Grande Western RR follows the river canyon, passing remote points such as Bridgeport and Broughton.

Industry is represented by the Blue Creek Mines in the southwestern reaches and various Prospects scattered across the high desert terrain. Extensive public lands, including the Uncompahgre National Forest and Grand Mesa National Forest, cover the higher elevations. The map also records the winding paths of Unaweep Canyon and Dominguez Canyon, showcasing the drainage patterns that carved these mesas and ridges over time.
