Degan Mountain and Sheephorn Mountain define this section of Lemhi County, characterized by a complex network of high-elevation drainages and basins. The presence of the Twin Peaks Mine in the northeastern quadrant suggests a history of resource extraction common to this part of Idaho. This 2011 survey illustrates how the landscape is segmented by significant watercourses like North Fork Iron Creek and South Fork Iron Creek, which converge as they flow toward the east. Isolated water sources such as Corbett Spring Number 1 and Sheephorn Spring are critical landmarks in this environment, while large alpine depressions like Badger Basin and Peel Tree Basin provide distinct geographical markers between the peaks. The map detail reflects the drainage patterns of Rattlesnake Creek and Deer Creek, illustrating the natural conduits through the mountains.
