2021 Map of Divide Lake

About this map

Yellowstone National Park and the Gallatin National Forest meet at the boundary of Wyoming and Montana, defining a landscape shaped by the headwaters of the Gallatin River. The terrain is characterized by a dense network of backcountry routes, including the Bacon Rind Creek Trl, Fawn Pass Trl, and Bighorn Pass Trl, which provide access through high-elevation basins and past water bodies such as Divide Lake. The presence of numerous drainage features like Grayling Cr, Snowslide Cr, and Terminal Monument Cr illustrates the complex hydrology of this mountainous divide. US Highway 191 serves as the primary corridor through this protected wilderness, following the river valley while connecting established trails to the interior of the park system.
