About this map

Wallrock is situated at the boundary of Gallatin and Park Counties, where the high ridges of the Gallatin National Forest meet the lower drainage basins. The landscape is defined by its complex hydrology, with the N Fork Muddy Cr, Middle Fork Muddy Cr, and S Fork Muddy Cr all converging to form the primary Muddy Cr channel. Significant elevation changes are marked by features like Elkhorn Ridge and the Wallrock Basin, creating a terrain that historically influenced the placement of mountain roads.

The human imprint on this area is seen through a network of rural routes such as Big Muddy Creek Rd, Keister Hardy Rd, and Teepee Ln, which provide access to the foothills and timberlands. While much of the territory remains under forest protection, the presence of Coal Gulch points to the area's mineral prospects. This map captures the intersection of public forest management and private landholdings in the Montana backcountry.
