About this map

The Pend Oreille River corridor defines the southern edge of this Idaho territory, serving as a primary transportation artery in the late 1960s. Parallel tracks of the Great Northern and Spokane International railroads trace the riverbank, passing through the small community of Wrencoe and near Little Muskrat Lake. To the north, the landscape shifts abruptly into the high-elevation terrain of the Kaniksu National Forest.

This rugged interior is dominated by a complex network of drainages such as Tarlac Creek and Carr Creek, while prominent summits like Bald Mtn and Gisborne Mtn overlook a system of jeep trails. Notable landmarks include the Priest River Experimental Forest and isolated clearings like McCormack Meadows. The map provides a clear picture of the mid-century timber and rail infrastructure that supported this section of Bonner County before modern development altered the valley floor.
