In two very different landscapes.
The photo of the unnamed waterfall on the left was taken the first day on the Rocky Mountaineer, in the sere desert mountains. And on the right is another picture of Pyramid Falls. Everyone on the train, and the Rocky Mountaineer website, called it that but when I first looked it up online, I found an entry in Wikipedia for Pyramid Creek Falls, which seems to be the same waterfall -- difficult to see except from the train tracks, and trains slow down so their passengers can get a good look at it. As ours did.
Whatever it's called, it's beautiful.
