Sahara Desert Bordered by Mountains and Lakes in Libya, Chad and Niger – November 15th, 201022.9N 14.7E
While the center part of this image is covered in yellow Sahara Desert sands, several other interesting geographical features can be observed by the edges.
The dark brown area in the upper right corner is the Tibesti Mountains, a group of mostly inactive volcanoes in northern Chad and extending a short distance into southern Libya.
Lighter brown in color and showing more circular patterns at the center left edge are the Aïr Mountains, in northern Niger, within the Sahara desert. The part of the Sahara east of the massifs is also known as the Ténéré Desert.
The green area by the bottom edge is Lake Chad, a shallow but large lake surrounded by wetlands in central Chad, on the edge of the Sahara Desert. In the full image, the yellow sands of the Sahara can be seen giving way to less arid lands to the south.
Finally, visible only at the top of the full image, is the Haruj volcanic field in central Libya. This large field contains many volcanoes, craters and lava flows.
