I just love the names of the mountains. Beartooth. Sawtooth. Elkhorn. Gallatin. Absaroka -I don't even know how to pronounce this but however you say it sounds cool.
Bitterroot. Big Horn. Anaconda - which is cool although it sounds out of place in Montana. Big Belt. Big Sheep. Chalk Buttes. Tendoy. Coeur d'Alene - I'm not much a fan of the French (aside from their cooking) but this name is just sexy. And my favorite, the Crazies.
