This peak is not in the book.
I ignored Sheephorn Mountain when I wrote the book because it has a road to the summit. Big mistake! This is an impressive peak with great views. The peak is located on the Eastern Edge of the Salmon River Mountains between Challis and Salmon. To reach the peak, take US-93 for 23 miles south of Salmon or 34 miles north of Challis. Turn onto Iron Creek Road and follow it for 4 miles. Then turn left onto Peel Tree Road, which becomes FS-083 in 6.8 miles.
Another 2.7 miles on FS-083 will take you to a saddle and a junction with the Sheephorn Mountain Road. The road is steep but great up to this point. Turn left at the junction and follow the rough road for another 5 miles to the summit. I recommend a high-clearance vehicle for the last 5 miles. You can park at any point and hike or ride a mountain bike to the summit. The lookout is no longer in use but is still in fair condition.
Although the peak has only 815 feet of prominence, it seems taller because of the precariously perched lookout, the depth of the nearby Salmon River Canyon, and the fact that higher terrain is a long distance away. I have never had a better view of the Northern Lemhi Range and you can see as far south as Mount Borah. The view of the surrounding Salmon River Mountains provides a seldom-seen perspective on how large the range is. Class 1. USGS Degan Mountain
