The Grand Canyon

The Grand Canyon has been touted as the Eighth Wonder of the World ever since John Wesley Powell braved the raging whitewater in its depths in 1869. It's inarguably the most overexposed icon of the American landscape — every year, 5 million people come to gawk into the abyss, and you have to wonder if the millions of rolls of film shot here through the generations might come close to filling the canyon from river to rim.
