About this map

Wallrock Ridge and the surrounding Wallrock Basin define this landscape along the boundary of Gallatin and Park Counties. This topographic record, compiled as part of a Bureau of Reclamation program for the Missouri River Basin development, details a high-elevation environment dominated by the Gallatin National Forest. The drainage patterns are clearly visible, from the northern flow of Cottonwood Creek to the convergence of the North, Middle, and South Forks.

A notable man-made feature is the Kistner-Hardy Dam on the South Fork, indicating the mid-century focus on water management in the region. The map also traces narrow features like Coal Gulch and the southern passage of Dry Creek and Muddy Creek, which cut through the complex terrain. While largely devoid of major settlements, the presence of specific family-named infrastructure and well-defined ridge lines provides essential geographic context for the region's land use in the early 1950s.
