2023 Map of May Mountain

About this map

May Mtn stands as a central topographic anchor within this portion of the Lemhi Range, where the boundaries of the Salmon National Forest and Challis National Forest meet. This high-altitude drainage network is defined by steep ridges and narrow canyons, with water moving through Hayden Creek to the northeast and Morgan Creek to the southwest. The landscape is marked by a sophisticated system of backcountry access points, including the Little Morgan-Morse Creek Trl and the Patterson-Morse Creek Trl, which follow the natural contours of the steep terrain. For those studying the region, the map reveals how historical pack trails and modern forest roads, such as Morse Creek Rd, have long served as the primary arteries through these protected lands, connecting disparate watersheds across the mountain crests.
