About this map

Lookout Pass serves as a critical geographic gateway along the high border between Idaho and Montana, marking a historical intersection of transport and topography. This area is characterized by the convergence of the Coeur d'Alene National Forest, Lolo National Forest, and St. Joe National Forest. The map documents early overland routes including the Old Yellowstone Trl and the Mule Team road, which traverse the divide near Runt Mtn.

A network of drainage systems defines the watershed, with the S Fork Coeur d'Alene River flowing westward and the Saint Regis River heading east from Saint Regis Lake. Engineering feats of the early 20th-century railroad era are evident at the southern end of the sheet, notably the Saint Paul Pass Tunnel near East Portal and Roland. These features illustrate the complex logistics of crossing the Bitterroot Mountains before modern interstate improvements.
