Run the rapids of the Colorado River through one of the seven wonders of the world whose origins began as far back as two billion years ago. Walk from rim to rim and meet the people of the blue-green water. Imagine the daring of John Wesley Powell as he and his companions made not one, but two, expeditions down the Colorado River, gathering geological and geographical information. There's much to be explored in this extensive issue about the history of this awe-inspiring chasm. And don't forget your trail snack!
