2016 Map of Iliff

About this map

The town of Iliff and the smaller clusters of Selma and Griff define the settlement pattern of this Logan County landscape along the South Platte River. The area is characterized by a sophisticated network of water management, vital for high-plains agriculture. Major infrastructure like the Iliff Platte Valley Ditch, Lone Tree Ditch, and the North Sterling Outlet Canal trace the contours of the valley, feeding into storage areas like Breidenbach Reservoir. North of the river, the terrain rises into draws and creeks such as Trap Draw, Sevenmile Creek, and Lewis Creek. This map documents the rural road grid, including Railroad Avenue and Logan Avenue, which parallel the historical rail corridor that facilitated the region’s growth. These features illustrate the enduring relationship between the river, irrigation engineering, and the small communities that emerged to support local industry.
