Thanks for an interesting page. I've always wondered if anyone has ever come up with a combination rating that would take into consideration prominence, easiest route to the summit (Class, YDS etc) and approach mileage to have a list of the overall toughest peaks to climb. Definitely it would be more subjective, I know.
#60 doesn't appear on other similar lists. I believe because the peak is just over the border in Montana
I suppose even though the summit isn't in Idaho, if any point within the Idaho border has 2000' prominence it still counts.
