Lake Tharthar, Iraq and the Al-Nefud Desert in Saudi Arabia – November 2nd, 201032.2N 41.9E
The green areas in the upper part of this image are situated around the Tigris and Euphrates Rivers and the valley between them. Also located between the two rivers is Lake Tharthar, the largest lake in Iraq.
The golden sands stretching across the lower part of the image are part of the Al-Nefud desert in the northern part of the Arabian Peninsula. Occupying a great oval depression, the desert is 180 miles (290 km) long and 140 miles (225 km) wide, with an area of 40,000 square miles (103,600 km²). The Nafud is an erg, noted for its sudden violent winds, which account for the large crescent-shaped dunes.
