About this map

The Colorado River carves through the southern landscape of this Mesa County region, separating the agricultural plains of the Grand Valley from the intricate canyonlands to the south. In the north, the small settlements of Mack, Loma, and Grand Valley are connected by a network of irrigation systems, including the Grand Valley Canal and Loma Drain, which support the local ranching and farming economy. To the south, the terrain rises sharply into a series of sandstone formations and deep cuts, most notably Pollock Canyon and Devils Canyon.

This high-desert environment is marked by numerous natural arches and rock formations, such as Centennial Arch, Window Rock Tower, and Finger Arch, which serve as significant landmarks for those navigating the backcountry. Recreational use of the land is evident through named trail systems like Lion's Loop and Mary's Loop that skirt the rim of Horsethief Canyon. The map also captures the path of the Kiefer Extension Grand Valley Canal, illustrating the complex water management required in this arid Colorado climate.
