About this map

Elkhorn National Forest dominates the western topography of this 1950s survey, where the high terrain of Ridge and the prominent Wallrock formations define the local watershed. This area, straddling the border of Gallatin and Park counties, serves as a significant drainage basin for several mountain streams. The convergence of the North Fork, Middle Fork, and South Fork feeds into a central valley where water management is evident at the Kistner-Hardy Dam.

The map reveals a landscape shaped by natural erosion and light resource infrastructure during the post-war development of the Missouri River Basin. Deep canyons such as Pole Gulch and the wide Wallrock Basin demonstrate the complex geography of the Montana high country. Smaller tributaries like Cottonwood Creek, Muddy Creek, and the seasonally dry Dry Creek suggest a terrain where water access was a primary factor in early land use and surveying.
