1988 Map of Sphinx Mountain

About this map

Sphinx Mountain and the distinctive formation known as The Helmet dominate this high-altitude landscape within the Lee Metcalf Wilderness. This 1988 provisional survey documents a transition zone between the Gallatin National Forest and the Beaverhead National Forest, characterized by steep drainage networks like McAtee Basin and Yellow Mule Creek. The presence of the Yellow Mule Ranger Cabin and the Manley Camp settlement reflect the area's history of forest management and early backcountry habitation. A complex system of named pack trails connects remote landmarks, including the Indian Crossing on Indian Creek. The mapping of the Bear Creek Wildlife Mgmt Area alongside these wilderness boundaries illustrates the era's focus on conservation and public land division in Madison County.
