The American Southwest is canyon country, rocks carved by rivers, forming breathtaking formations that rival any monuments built by humans. A journey through the southwest is one through national parks such as Zion, Bryce, Grand Canyon and Arches. Lake Powell is a playground for lovers of water sports, with slot canyons providing hidden coves great for kayaking or stand-up paddle boarding. Layer by layer, the rocks tell the story of millions of years of geological history and thousands of years of human habitation.
