Algeria - December 22nd, 2011

This shows Algeria, the largest country in Africa, the Arab world, and the Mediterranean. Most of the coastal area is hilly, sometimes even mountainous, and there are a few natural harbours. The area from the coast to the Tell Atlas is fertile. South of the Tell Atlas is a steppe landscape, which ends with the Saharan Atlas; further south, there is the Sahara desert.

The Tell Atlas merge with the Saharan Atlas in eastern Algeria. Between the two ranges lie vast plains and highlands. The vast mountain ranges of Aures and Nememcha, occupy northeastern Algeria and are delineated by the Tunisian border. The Ahaggar Mountains, also known as the Hoggar, are a highland region in central Sahara, southern Algeria.

Sand Dunes of the Grand Erg Oriental, Algeria – October 7th, 2010

Algeria - August 27th, 2010

This image focuses on the Grand Erg Oriental, situated for the most part in Saharan lowlands of northeast Algeria. An erg is a field or “sea” of sand dunes in the Sahara desert.

The Grand Erg Oriental covers an area some 600 km. wide by 200 km. north to south, making it the largest erg in Algeria. The erg’s northeastern corner spills over into neighbouring Tunisia.

Upon opening the full image, many individual rows of high sand dunes can be observed. Also visible at the bottom of the full version are the Ahaggar Mountains. If any water were to reach the erg, it would be from mostly dry and buried rivers originating in those mountains and flowing down and northward.

The image thumbnail focuses on ergs (seas of sand dunes) and mountains in eastern Algeria (left half) and western Libya (right half). The two mountain ranges are the Tassili n’Ajjer (center, dark brown), and the Ahaggar Mountains (bottom center, lighter brown). Some dust can be seen blowing over the Ahaggar range.

The full image reaches from the shores of Tunisia (top) to the Aïr Mountains in Niger (bottom). The Kerkennah Islands (above) and the island of Djerba (below) can be seen near the Tunisian coast. Some greenish sediments can be seen around the islands.

Algeria - June 30th, 2010

Two mountain ranges are visible amidst the orange sands of the Sahara Desert in Algeria: the Tassili n’Ajjer, with a pointed triangular shape (center), and the Ahaggar Mountains to the south, separated from the former by a stretch of light sands.

Upon opening the full image, some dust appears to be hanging in the air to the south of the mountains. This later became a more intense dust storm (click here for article).

Algeria - July 4th, 2010

Strong winds kick up clouds of sand and dust from the Sahara Desert over Algeria.The dust is whitish tan in color like the desert sands to the south, in contrast with the golden orange tones of the expansive ergs to the north.

The lower half of this image is mostly veiled by the shifting sands. Just below the center, the Ahaggar Mountains are mostly obscured; only the northwestern part of the range can be seen. In the upper half, several bands of dust can be seen blowing over the brown mountains of the Tassili n’Ajjer range.
