2020 Map of Alta

About this map

Alta sits at the northern edge of this high-country landscape where the W Fork Bitterroot River meets the drainages of Hughes Creek. This area of the Bitterroot National Forest is defined by its deep canyons and prominent ridges, including Than Wilkerson Ridge and Thunder Mountain. The map details a network of forest access routes like the Alta Meadow Trl and Horse Creek Pass Rd that navigate the steep terrain between Beaver Point and the state line. Near the southern border, the boundary between Montana and Idaho follows the high divide, crossing into the Salmon National Forest. Here, remote water sources such as Marlin Spring and Saddle Spring are documented near the headwaters of Squaw Creek, marking the transition into the Lemhi County wilderness.
