1997 Map of Mount Jefferson

About this map

The Continental Divide Scenic Trail snakes along the high ridges of the Centennial Mountains in this late-twentieth-century study of the Montana-Idaho border. The landscape is defined by its administrative and scientific designations, dominated by the Sheep Experiment Station and the Centennial Mountains Wilderness Study Area. In the north, the terrain drops into the Centennial Valley, where the edges of the Red Rock Lakes Nat Wildlife Rfg appear near Red Rock Creek. Notable peaks including Mount Jefferson and Nemesis Mountain anchor the high country, while remote water sources like Hidden Lake and Icehouse Creek illustrate the watershed's complexity. The presence of the Alaska Basin and Rock Creek Basin highlights the glacial-carved nature of these summits, serving as a record of high-altitude land management just before the turn of the millennium.
