The Colorado Rockies exceed the Alps as a mountain panorama.

Evidence

We forded the river, whose course is marked the whole way by a fringe of small cotton-woods and aspens, and traveled hour after hour with nothing to see except some dog towns, with their quaint little sentinels; but the view in front was glorious. The Alps, from the Lombard Plains, are the finest mountain panorama I ever saw, but not equal to this; for not only do five high-peaked giants, each nearly the height of Mont Blanc, lift their dazzling summits above the lower ranges, but the expanse of mountains is so vast, and the whole lie in a transparent medium of the richest blue, not hazesomething peculiar to the region. — Isabella L. Bird, A Lady’s Life in the Rocky Mountains, 123
