2014 Map of Hatfield Mountain

About this map

Gallatin National Forest dominates this mountain landscape in Gallatin County, characterized by high ridges and a network of named drainages. The small settlement of Sedan sits in the southeastern corner, serving as a landmark in an area otherwise defined by significant elevations like Hatfield Mtn and Red Rock Mtn. The transport pattern is dictated by the terrain, with Sixteen Mile Rd following the northern canyon and Petterson Rd providing access from the south. This area is heavily dissected by seasonal and perennial waters, including Middle Fork Sixteenmile Cr and Snowslide Cr. The map reveals the intersection of forestry management and early settlement routes, with topographic features such as Coal Gulch and Miller Gulch suggesting the local history of land use and extraction in these high-altitude basins.
