Waterton Lakes NP is a prairie-meets-mountain park. We drove through rolling grasslands for miles from Calgary then they just butt right up against the mountain slopes. It is marvelous terrain. The Railroad (the US Great Northern Railroad no less) built one of their opulent hotels here, the Prince of Wales. It looks like a huge Alpine Villa perched high above the valley. They serve high tea overlooking the lake. A little too snobby for me but a great bit of architecture. I prefer the philosophy applied in the US of making the Inns blend or reflect the environment.
