canyon

The Grand Canyon, carved out by the Colorado River, is found in the south-western state of Arizona. Yellowstone National Park, established as the United States' first national park in 1872, is located mostly in the northern state of Wyoming, but parts of it are in the nearby states of Montana and Idaho. It contains some of the world's best-known geothermal features, including the geyser Old Faithful. (Visiting Old Faithful as a child, I remember being quite disappointed, as it is far from being the most spectacular geyser in the park. It is, however, incredibly predictable in its release of steam, hence its name.) The Everglades is a large wetland area in the south-eastern state of Florida.
