Sahara

Two shakes. Niger River

The Niger River is a relatively "clear" river, carrying only a tenth as much sediment as the Nile because the Niger's headlands are located in ancient rocks that provide little silt.[3] Like the Nile, the Niger floods yearly; this begins in September, peaks in November, and finishes by May.[3]

Dunes in Sahara

The Sahara[1] in North Africa, is the one of the largest deserts in the world. Antarctica is also a desert, and is larger.[2]

It is bounded by the Atlantic Ocean, the Atlas Mountains, the Mediterranean Sea, the Red Sea, and the Sahel region. Inside it are parts of many countries, including Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad, and The Sudan. Most parts are uninhabited, but some people manage to survive in places where there is water.[3]

The Sahara Desert is about 9,065,000 square kilometers in size. It has been both larger and smaller at different times. Ater the last ice age it became more fertile, then dried up again. It is the hottest place on the Earth, but not the driest. The driest is the Atacama Desert in South America. The Sahara has about the same size as the whole United States.

Very nice!

fractal is a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole
