1968 Map of South Putnam Mtn

About this map

The Portneuf Range dominates this late-1960s landscape, rising to the heights of Mt Putnam and South Putnam Mtn along the border of Bannock and Caribou counties. The settlement of Barclay is positioned along the western foothills, where Ross Fork and Mill Creek emerge from the high country. This survey illustrates the convergence of different land management eras, showing the southern Fort Hall Indian Reservation Boundary meeting the northern edge of the Caribou National Forest. Local infrastructure is defined by specialized routes such as the Buck Skin Pack Trail and Mc Nab Road, which navigate the drainage basins of Thirty Day Creek and Rapid Creek. The map documents a period when access to these peaks relied on a network of jeep trails and historic pack routes through the basins.
