Yellowstone National Park - Grand Canyon of the Yellowstone
Grand Canyon of the Yellowstone
Yellowstone's Grand Canyon may not be as big as the Grand Canyon in Arizona, but it is nonetheless breathtaking. If you ever wonder why the park is called yellowstone, these picture taken in the Grand Canyon area might give you some clue. The 1,200 feet-deep V-shape valley is carved by glacial movement and melted water starting some 14,000 years ago. It is quite colorful because of the rusting of the iron compound in the volcanic rocks.
