1969 Map of Grandmother Mountain

About this map

St Joe National Forest defines the landscape of Shoshone County in this 1969 survey, revealing a network of drainage basins and high summits that shaped early Idaho logging and mining access. The map tracks the elevation from the headwaters of Marble Creek and the North Fork St Maries River up to the prominent peaks of Grandmother Mtn and Grandfather Mtn. The terrain is marked by a legacy of resource extraction and transit, evidenced by named watercourses like Placer Creek and Gold Center Creek, which hint at the region's mineral history. A complex system of transit, including the Pack Trail and various Jeep Trails, connects remote points such as Davies and Cornwall Point. These paths follow the natural contours of the land, crossing over Freezeout Saddle and along Freezeout Ridge, providing a look at the backcountry infrastructure used by foresters and early explorers.
