About this map

Gallatin National Forest terrain dominates this 1951 survey, where the high elevations of Wallrock Ridge separate the drainage of Cottonwood Creek from the rugged Wallrock Basin. The landscape is defined by the headwaters of the Muddy Creek system, which converges at the Kistner Hardy Dam. To the west, Coal Gulch cuts deeply through the timbered slopes, illustrating the complex topography along the Gallatin and Park County line.

The mapping reflects an era of resource development in the Missouri River Basin, conducted by the Bureau of Reclamation and the USGS. The detailed hydrography of the North Fork, Middle Fork, and South Fork Muddy Creek highlights the critical water management infrastructure of the period, while the inclusion of local landmarks like Dry Creek provides essential context for family historians studying the homesteads and ranches of south-central Montana.
