Aïr Mountains by Ténéré Desert, Niger

18.2N 7.9E

January 15th, 2012 Category: Deserts, Mountains

Niger - January 6th, 2012

The Aïr Mountains form a triangular massif, located in northern Niger, within the Sahara desert. They rise to more than 6,000 ft (1 830 m) and extend over 84 000 km², and have an average altitude between 500 and 900 m. The mountains consist of nine almost circular massifs rising from a rocky plateau, bordered by the sand dunes and plain of the Ténéré Desert to the east (right edge).

The massif is a plateau consisting of a Cambrian age erosion surface on Precambrian metamorphic rocks, punctuated by a series of flat-topped, granite intrusion peaks, which include Mont Idoukal-n-Taghès (Niger’s highest point at 2022 m), Mont Tamgak (1988 m), Mont Greboun (1944 m), and others. The massif contains volcanic features including the extinct calderas, volcanic cones, and tuff rings.

Niger - October 30th, 2011

Visible as a dark brown area on the left side of this image of Niger are the Aïr Mountains, which consist of nine almost circular massifs rising from a rocky plateau, bordered by the sand dunes and plain of the Ténéré Desert to the east.

The massif is a plateau consisting of a Cambrian age erosion surface on Precambrian metamorphic rocks, punctuated by a series of flat-topped, granite intrusion peaks, which include Mont Idoukal-n-Taghès (Niger’s highest point at 2022 m), Mont Tamgak (1988 m), Mont Greboun (1944 m), Adrar Bous, Fadei, Chirriet, Taghmert, Agueraguer, Takaloukouzet, and Goundai.

The massif contains volcanic features including the extinct caldera of Arakao, Cenozoic lava flows of hawaiite to trachyte composition, volcanic cones, tuff rings and one of the largest ring dike systems in the world.

Air Mountains and Lake Chad Separated by Sahara Desert, Niger and Chad

Niger and Chad - November 9th, 2010

The grouping of almost circular brown patches in the upper left quadrant are the peaks and plateaus of the Aïr Mountains. They are located in northern Niger, rising up above the Sahara desert. The light tan, sandy part to their east is a part of the Sahara called the Ténéré Desert.

Moving southeast from the mountains, one comes to a body of water surrounded by green wetlands at the edge of the Sahara Desert. The body of water is Lake Chad, important for providing water to more than 20 million people living in the four countries that surround it (Chad, Cameroon, Niger, and Nigeria).

Niger - October 13th, 2010

The Aïr Mountains (also known as the Aïr Massif) are located in northern Niger, within the Sahara desert. They consist of nine almost circular massifs, several of which can be easily identified in the thumbnail, rising from a rocky plateau, bordered by the sand dunes and plain of the Ténéré Desert to the east.

The mountains extend over an area of 84 000 km² and reach heights of over 6,000 ft (1 830 m). The Aïr plateau, however, has an average altitude between 500 and 900 m. The plateau and mountains form an island of Sahel climate which supports a wide variety of animal and plant life and many pastoral and farming communities.

Niger - March 5th, 2010

The Aïr Mountains stand out as unusually dark granite peaks and plateaux against the sand-covered lowlands of the Sahara Desert in northern Niger. These mountains reach heights of more than 6,000 ft (1 830 m) and extend over an area of 84000 km².

The peaks and plateaux are interrupted by sandy valleys and seasonal wadis. The massif has some volcanic features, including the cadera of the extinct Arakao. To the east, the sand dunes of the Ténéré Desert are visible.
