Perhaps the most unmistakably American landmark is Mount Rushmore, a national memorial located in South Dakota. Constructed in the early 20th century, Mount Rushmore depicts the faces of four former American presidents, each of which is carved and blasted from the side of a rock face.
This incredible natural attraction is one of the most visited places in the United States. Carved out by the Colorado River, the Grand Canyon cuts deep into the landscape, creating dramatic cliff walls and ledges. Visitors standing on the rim of the canyon can see down to the canyon floor a mile below, and look out over the ridges and cliffs that run as far as the eye can see.
