About this map

The settlement of Alta serves as a focal point within the northern reaches of the Bitterroot National Forest, situated where the West Fork Bitterroot River meets Hughes Creek. This high-country landscape is defined by its extensive network of drainage-based paths and ridgeline terrain, notably Than Wilkerson Ridge and the prominent Thunder Mtn. The map captures a topography shaped by water and elevation, with named features such as Stevens Gulch and Molloy Gulch cutting through the slopes.

Logistics in this portion of the Montana-Idaho border region rely on a combination of primitive routes and forest service trails. Key access points include the Hughes Creek Rd and W Fork Rd, which connect more remote interior paths like the Chicken Creek Trl and Deer Creek Trl. The presence of numerous springs, including Marlin Spring, highlights the critical water sources for the region's wilderness management and early backcountry travel.
