1963 Map of Deadhorse Ridge

About this map

Craig Mts and the confluence of the Salmon River and Snake River define this rugged corridor of the Pacific Northwest during the early 1960s. The map captures a landscape shaped by remote ranching and hard-rock mining along the Idaho-Oregon border, where the Imnaha River cuts through the steep canyons of the Wallowa National Forest. Economic activity is centered on narrow river bars and deep gulches, evidenced by the presence of Mine Ruins at Eureka Bar and a string of prospects including the Mountain Chief Mine, Bonnie Doone No 1 Mine, and Hilliker Mine.
