About this map

The Colorado River carves a deep valley through this portion of Garfield County, separating the prominent Grand Hogback in the north from the high ridges of the south. This 2016 survey documents a landscape defined by an intricate network of irrigation, where the Grass Valley Canal, Lower Cactus Valley Ditch, and Ware and Hinds Ditch redirect water from the river and reservoirs to support agriculture on the benches. The town of Silt sits as a primary hub along the river corridor, while the settlement of Antlers and the eastern edge of Rifle anchor the transportation routes through the valley floor.

Industrial and transit infrastructure is central to the area's modern character, highlighted by the Garfield County Regional Airport positioned on the flat expanses west of Mamm Creek. Beyond the developed river bottom, the map reveals diverse terrain features like Graham Mesa and Cactus Valley, along with significant water storage at Grass Valley Reservoir and Rifle Valley Reservoir. Local landmarks such as Weible Peak and Harvey Gap provide vertical context to this transition between the river valley and the rising plateau country.
