Semien Mountains, Ethiopia

The Semien Mountains are the highest parts of the Ethiopian Plateau (more than 2,000 meters; or 6,560 feet). They are surrounded by a steep, ragged escarpment (step), with dramatic vertical cliffs, pinnacles, and rock spires. Although the plateau lies in the latitude of the Sahara–Arabia deserts, its high altitude makes for a cool, wet climate. In fact, the Semien Mountains are one of the few places in Africa to regularly receive snow, and they receive plentiful rainfall (more than 1,280 millimeters, or 55 inches). The moderate climate is shown by light green vegetation on the mountains, compared with the brown canyons, which are hot and dry.


Astronaut photograph ISS016-E-10784 was acquired on November 16, 2007, with a Kodak 760C digital camera fitted with a 180 mm lens, and is provided by the ISS Crew Earth Observations experiment. The image was taken by the Expedition 16 crew, and it is provided by the Image Science & Analysis Laboratory, Johnson Space Center. The image in this article has been cropped and enhanced to improve contrast. Lens artifacts have been removed. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of the Earth. Caption by M. Caption by M. Justin Wilkinson, NASA-JSC.
