You can tell a lot about a mountain from its colour
The more you travel through the Rocky Mountains, the more you’ll notice subtle gradients in colour from peak to peak. That’s no trick of the light. In fact, you can actually learn a lot about the mineral content of the rock itself simply by reading its hue. A mountain with a reddish-orange tint likely has a significant iron content, for instance. As you might expect, given the colour of tarnished copper, a mountain containing that metal often appears greenish. A yellow mountain, on the other hand, suggests a high concentration of sulphur. On occasion, as in the striking Painted Bluffs near Kamloops, British Columbia, you can see many of these mineral deposits across the same multi-coloured rock face. You’ll get an amazing view of the Painted Bluffs onboard two of Rocky Mountaineer’s most popular routes, “First Passage to the West” and “Journey Through the Clouds.” The famed luxury train is the best way to experience not only this breathtaking spectacle, but a whole host of awe-inspiring sights through the Canadian Rockies, including the aptly named Rainbow Canyon, closer to Lytton, B.C.
