About this map

Iliff serves as the focal point of this Logan County landscape, situated along the northern banks of the South Platte River and the corridor of the Union Pacific railroad. The map documents a sophisticated agricultural irrigation network vital to the High Plains, featuring an extensive system of laterals and ditches such as the Sterling Outlet Canal, Iliff Ditch, and Valley Ditch.

Evidence of shifting settlement patterns is visible near the tracks at Selma (Aban'd), while numerous family-named landmarks like McKenzie Pond and Lewis Creek punctuate the terrain. The presence of a Gravel Pit and several Windmill sites highlights the area's dual reliance on subterranean resources and the water-management infrastructure that transformed the dry valley into a productive corridor. Waterways like Sevenmile Creek and Griff Creek feed into the broader river system, defining the drainage patterns of this eastern Colorado region.
