About this map

The Gunnison River carves through this high-desert landscape in Mesa County, where the small settlement of Bridgeport serves as a lone outpost near the river's edge. The terrain is a complex system of elevated plateaus and deep incisions, including the prominent Triangle Mesa and Steamboat Mesa. Water management and natural drainage define the area, with Big Dominguez Cr and its tributaries, such as the Dry Fork Big Dominguez Cr, threading through steep-walled corridors like Dominguez Canyon.

Large, flat upland areas such as Cactus Park and Poverty Flat provide distinct topographical contrast to the neighboring canyons. Local history is reflected in the naming of isolated landmarks like No Mans Mesa, Star Mesa, and Ninemile Hill. The map also captures the boundary between Mesa and Delta counties as it traverses the southern end of Lightning Basin, providing a detailed look at the hydrology and landforms that have historically shaped travel and ranching in this part of Colorado.
