About this map

Anderson Peak stands as a prominent high point in this remote section of Custer County, overlooking a complex system of drainages and natural springs. The landscape is defined by its seasonal water sources, including the sequential Horse Basin Spring Number 1 and Horse Basin Number 2, which feed into the central Horse Basin area. Further north, the terrain transitions toward Corral Basin and Broken Wagon Cr, where elevation markers reveal the steep topography of the region.

Remote tracks such as Road Creek Rd and Walker Way provide the only significant access through these mountain basins. For researchers, the map provides a clear look at the network of springs like Spar Mountain Spring and Douglas Spring that have long dictated the movement of livestock and wildlife across this high-altitude landscape. The drainage patterns of Road Cr and Bear Cr reflect the watershed's role in the broader Idaho backcountry.
