1989 Map of Ashton

About this map

The confluence of the Henrys Fork and Fall River defines the landscape surrounding Ashton, Idaho, during this late-twentieth-century period. This map captures a transition from the agricultural lowlands near Marysville and Grainville to the high timber of the Targhee National Forest and the southwestern edge of Yellowstone National Park. The Union Pacific rail line and U.S. 20 serve as primary transportation corridors, connecting the dispersed settlements of Kilgore, Drummond, and Macks Inn with the vast recreational and wildlife lands of the Harriman State Park and the Sand Creek Wildlife Management Area. Geologic history is visible through features like Split Rock, Butte Crater, and the extensive Sand Dunes to the southwest. The presence of the Island Park Reservoir and numerous creeks such as Squirrel Creek and Conant Creek highlights the region's importance for irrigation and outdoor recreation.
