This peak is not in the book.
Packer John Mountain is located in the North Fork Range, east of ID-55. The peak has a long North-South summit ridge which was once the home of a fire lookout. The true summit is farther south and almost 50 feet higher. USGS Packer John Mountain

Access and Routes (Class 2)
The North Fork Range has a tangle of roads. Offering driving directions that you could rely upon is beyond me at this point. Google Maps provides directions from the south that I believe use a recently-closed road. Google Maps directions from Smiths Ferry should work but I have not field checked them. John Platt and Dave Pahlas accessed the peak from Big Eddie Campground along ID-55. You can read about their long, brushy climb by using the links below. By using a road approach, you can get to within 150 vertical feet of the summit.
