2017 Map of Hatfield Mountain

About this map

Hatfield Mountain and Red Rock Mtn dominate this high-elevation landscape in Gallatin County, defined by the deep drainages of the Gallatin National Forest. The settlement of Sedan sits at the southern edge of the quadrangle, where the terrain begins to transition from the steep gulches of the northern peaks toward more accessible valley floors. The drainage network is complex, characterized by the Middle Fork Sixteenmile Cr and various ephemeral and seasonal flows like Snowslide Cr and Dry Fork. Local travel is dictated by the topography, with roads such as Sixteen Mile Creek Rd and Petterson Rd following the natural contours of the gulches. This survey provides a precise look at the forest boundaries and township lines, including t4n r6e and t3n r7e, illustrating how public land management and private holdings intersect in the Montana backcountry.
