In response to The Daily Post’s weekly photo challenge: “Scale.”
The Rub Al Khali (The Empty Quarter) is the world’s largest sand desert. It covers 250,000 square miles and stretches from the UAE in the North, touches Oman in the East and covers a huge portion of Saudi Arabia. The British explorer Wilfred Thesiger made two epic crossings of this inhospitable land back in the 1940s but today one normally crosses it via 4×4. This week’s snap of a camel caravan illustrates the sheer scale of the dune massifs which stretch across much of Arabia.
