2013 Map of Iliff

About this map

The S Platte River valley defines this part of Logan County, where a sophisticated network of irrigation channels supported agricultural life in the early 21st century. The settlement of Iliff serves as the primary hub, situated near the intersection of Us-138 E and Railroad Ave. The landscape is etched with complex water-management features, including the Iliff Ditch, Iliff Platte Valley Ditch, and the N Sterling Outlet Canal, reflecting the region's reliance on river-fed irrigation. North of the river, the terrain rises into draws and basins, featuring Lewis Creek and the Breidenbach Reservoir. Small railway-adjacent points like Selma and Griff mark the transit corridor running parallel to the river. This survey captures a moment when the rural road grid, defined by routes like CO Road 53 and CO Road 57, provided structure to a landscape shaped by both the natural flow of the South Platte and the engineering of the high plains canal system.
