The Sahara Desert In Western Algeria

Gemini 7 photograph of the Sahara desert southeast of Bechar in Western Algeria. The lower and left portions of the image show dunes, long ridges 8 to 16 km (5 to 10 miles) apart, 150 to 250 m (500 to 800 ft) high, and hundreds of km long. A wadi, or stream bed which is usually dry, the Oued Saoura, is at the upper right of the image, and is filled with water from a recent rain. To the left of it is a recently formed ephemeral lake. North is up. (Gemini 7, S65-63830)
