1962 Map of Allison Creek

About this map

The Salmon River carves a deep valley through this Lemhi County landscape, serving as the primary drainage for numerous tributaries like McKim Creek and Allison Creek. High elevation features like Goldbug Ridge and Long Ridge define the eastern terrain within the Salmon National Forest. This 1960s-era survey reveals the utilitarian footprints of mountain life, including scattered prospects and a Gravel Pit near the river’s edge. The distribution of waterways such as Poison Creek and Mud Creek illustrates a complex watershed where steep canyons meet the main river corridor. A network of jeep trails provides the only significant inland access, suggesting a period of limited development focused on resource exploration and forest management.
