1955 Map of Owl Ridge

About this map

The Illinois River and its numerous tributaries dominate this high-altitude landscape in Jackson County, where an intricate network of irrigation channels supported early 20th-century ranching operations. The map documents a specialized hydraulic economy, featuring several family-named outposts such as Burr Ranch, Vils Ranch, and the Illinois Ranch. Water management is the primary human imprint on the land, evidenced by an extensive system of ditches including the Pioneer Ditch, Midland Ditch, and Overland Ditch. These man-made watercourses connect larger water bodies like the Thirty one Reservoir and Rand Reservoir. The terrain transitions from the alluvial plains of the river valley up toward the prominent geological formations of Owl Ridge and Owl Mountain. Industrial activity is represented by the Gravel Pits located near the riverbank, while the presence of the Ish Baldwin road suggests early transit routes through the area.
