1955 Map of Ashton

About this map

The Continental Divide winds through this mid-century landscape, separating the high plateaus of Yellowstone National Park from the agricultural valleys of southeastern Idaho. In the west, the Centennial Mountains form a massive natural barrier along the Montana border, sheltering the Red Rock Lakes National Wildlife Refuge. The irrigation network of the Marysville Canal and Last Chance Canal supports the farming communities around Ashton and Marysville, while the Union Pacific railroad line pushes northward through Eccles Siding and Island Park Siding. This era shows the developed tourist corridor of the park at Old Faithful and Grant Village before modern traffic patterns fully reshaped the approach through the Targhee National Forest. The map captures the remote timber and ranching character of Kilgore and the high-altitude waters of Yellowstone Lake and Island Park Reservoir.
