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.
I know what you are saying. Especially lower on the list you get a lot of peaks that just happen to sit in the correct spot for a high prominence. For example, Mica Peak, Long Mountain, Moscow Mountain, and many others, have roads to the top.
I have seen some of the stats you are discussing and I think in the end no two mountain experiences can be the same. You can be on a class 3 scramble, and get snowed on in August and have the adventure of a lifetime. Or you can walk up Mr. Rainier on the perfect day without a care in the world. Just luck of the draw.
Anyway, my hope is that these lists get friendly competition going. I love seeing how other people are doing working on the list. Who knows, maybe someone, someday will come up with the perfect combo. Until then. We'll just have to keep climbing. :P
