2017 Map of Old Baldy Mountain

About this map

Old Baldy Mtn anchors this high-elevation landscape in Madison County, where the alpine terrain is divided between the Deerlodge National Forest and Beaverhead National Forest. This 2017 survey reveals an intricate drainage system defined by deep gulches and man-made water management features like Cornforth Ditch and Marsh Ditch. These irrigation efforts in the high country, such as the system feeding Smith Reservoir, indicate the historical necessity of diverting water across these slopes to support downstream agriculture or mining operations. The map details a network of specialized access points including Bear Gulch Rd and Wet Georgia Rd, which navigate the steep rises toward peaks like Smelter Mtn and Lava Mtn. High-altitude water bodies, notably Lower Boulder Lake and Mud Lake, sit within a series of named ravines like Independence Gulch and Montana Gulch, reflecting the region's complex topographical character.
