2020 Map of Ione South

About this map

Ione sits at the northern edge of this landscape, where the waters of Willow Cr and Rhea Cr converge. This area of Morrow County is defined by a deeply dissected plateau, where numerous named drainages such as McMillan Canyon, King Canyon, and Brenner Canyon carve through the high ground. The topography is anchored by the prominent Jordan Butte, a central landmark that rises above the surrounding network of canyons. The road network reflects a history of rural access and land management, with routes like Ione-Gooseberry Rd and Liberty School Rd cutting across the terrain. To the southeast, the steep descent of Rattlesnake Grade illustrates the challenging elevation changes characteristic of this region. This modern survey details the complex system of coulees and ridges that have shaped the agricultural and transport patterns of the high desert fringe.
