2011 Map of Half Moon Canyon

About this map

Greathouse Peak and Old Baldy anchor the high elevations of this Fergus County landscape, where deep drainages like Half Moon Canyon and No Name Canyon cut through the terrain. The hydrological pattern is defined by the headwaters of several systems, including East Fork Big Spring Creek and the southward-flowing Swimming Woman Creek. The mapping shows a sparsely populated area where human presence is marked primarily by isolated outposts such as Lewis Ranch and the winding course of Red Hill Rd. Movement through this high country relies on natural corridors like Half Moon Pass. The transition from the steep walls of Stovepipe Canyon to the more open reaches of Buffalo Creek illustrates the complex relief that defines this part of Montana.
