From giant mountains to vast deserts, an American photographer spent a year capturing the diverse and beautiful landscape of the United States. The breath-taking images were taken by Randy P. Martin, 30, of Portland, Oregon, who travelled hundreds of miles across America and documented the most diverse and beautiful settings along the way. For Randy, the past year has seen him undertake countless road trips, navigate his route with maps made from napkins - with the help of Google Earth, walk miles across fields of lava rock and wake at 3am to see sunrise at 14,000 feet
