The Uncompahgre River corridor defines this portion of the Western Slope, where the valley floor transitions into the elevated terrain of Log Hill Mesa and the Uncompahgre Plateau. The small settlement of Colona sits near the Montrose Co Ouray Co boundary, serving as a focal point for local history along with the nearby Colona Cem. Irrigation infrastructure, critical to the region's agricultural development, is represented by the McDonald Ditch and W Canal, which draw from the river to water the surrounding benchlands.
