I think I spelled Rainier as "Ranier"... or made an accidental typo. Knew it but missed that one. Finished with 11 which is currently the 56th percentile.
you almost never hear about matterhorn and you hear about montblanc nearly as much as mount everest, so I would definitely agree montblanc is more famous.
Though I guess it depends on how much toblerone you eat ;)
That Matterhorn is more famous than Mont Blanc is, at least, very disputable. (Matterhorn returns 17 million google hits. "Mont Blanc" gives 72 million).
I'd suggest changing the clue to "famous mountain in the Switzerland-Italy border".
At the risk of incurring American wrath, i think this is a little too North American centric I think. Some of the mountains in that region are internationally well-known, but many are not.
Is this the work of someone from Portland or Seattle? Two mountains each from Washington and Oregon, plus one across the border in BC - that's a quarter of the mountains on the quiz within less than a day's drive of each other. In fact you can go down the Pacific Coast of North America from Alaska to the Mexican border without passing through a state, province or territory without representation here. Even other parts of the US don't get a look in - nothing from the east, nothing from the Rockies, nothing from Hawaii. And then there's the matter of that little group of hills known as the Andes that don't turn up anywhere here.
Good quiz - but it doesn't need all those blanks. Could I suggest Nanga Parbat (9th highest in the World) as worthy of addition and surely more internationally famous than Garibaldi, Hood or Tambora?
There are other letters that could be included too. Ismoil Somoni Peak(The highest in the former Soviet Union), Qurnat as Sawda in Lebanon, and what about Uluru? That's a mountain. X and Y are a little tougher, but you could include Yushan, the highest in Taiwan.
Technically, Alaska is part of the continental USA so Denali should replace Whitney. Either that or change the question to the lower 48 or contiguous US states.
Anyway, the Matterhorn is also called Cervino (or Cervin in French).

Y = Yellowstone Caldera
