1995 Map of Arsenic Mountain

About this map

Medicine Springs and the northern reaches of the Sun River Game Preserve define this section of the Rocky Mountain Front in the mid-1990s. The landscape transitions from the high peaks of the Sawtooth Range and the Bob Marshall Wilderness down toward the Gibson Reservoir on the Sun River. This 1995 revision reveals a mix of remote high-country infrastructure and recreational outposts, including the K-L Ranch and the JJJ Wilderness Ranch. Traceable historical markers include the White Cabin (Site) and a Gaging Sta near the river, illustrating the importance of water management in this drainage. The drainage network is complex, with Arsenic Creek flowing off the flanks of Arsenic Mountain to join the South Fork Teton River in the north, while Mortimer Gulch and Big George Gulch carve the southeastern slopes.
