Boab Tree, Australia

A massive boab tree, close relative of the African and Madagascan baobabs, stands alone amid the golden grasses of a plain near the town of Wyndham in Western Australia. Much of Western Australia's 7,800 miles (12,500 kilometers) of coastline gives way to broad coastal plains, such as this one, that extend inland to the state's hot, dry central plateau, known as the outback.
