2014 Map of Upper Red Rock Lake

About this map

The Upper Red Rock Lake dominates the northwest corner of this map, situated within the wide expanse of the Centennial Valley. The landscape is defined by a dramatic shift from the lowlands of the valley floor to the high elevations of the Centennial Mountains, which form a natural barrier to the south. Along this high ridge, the Montana-Idaho state line follows the Continental Divide, marking the hydrological split of the continent. The southern half of the quadrangle is largely occupied by the Targhee National Forest, a terrain of high peaks including Sheep Mountain and Taylor Mountain. A network of high-altitude waterways, including Red Rock Creek and Middle Fork Sheridan Creek, drain these slopes. While the area is largely wilderness, human presence is traced through routes such as Red Rock Pass Road and Elk Lake Road, which provide access through the mountain passes.
