The Simien Mountains (Amharic: ስሜን ተራራዎች or Səmen; also spelled Simen and Semien), in northern Ethiopia, north east of Gondar in Amhara region, are part of the Ethiopian Highlands. They are a World Heritage Site and include the Simien Mountains National Park. The mountains consist of plateaus separated by valleys and rising to pinnacles. The highest Ethiopian mountain is Ras Dejen at 4,550 m with the second highest peak of Kidis Yared at 4,453 m; other notable peaks include Mount Biuat at 4,437 m.
Because of their geological origins, the mountains are almost unique, with only South Africa's Drakensberg range having been formed in the same manner and thus appearing similar. Notable animals in the mountains include the walia ibex, gelada, and caracal. There are a few Ethiopian wolves.
Geology and landscape

The Simien Mountains were formed prior to the creation of the Rift Valley, from lava outpourings between 40 and 25 million years ago during the Oligocene period. The volcano is believed to have spread over more than 5000 m2 and resulted in a thick sequence of basaltic lava some 3,000-3,500 m thick that was deposited on Precambrian crystalline basement. The major part of the Simien Mountains consists of remnants of a Hawaiian-type shield volcano. The Kidus Yared peak is situated near the middle of the shield volcano. Ras Dejen (4,533 m), Bwahit (4,430 m) and Silki (4,420 m) were formed from the outer core of this ancient volcano.
The extreme escarpment in Simien appears to be a precondition for the formation of the extended uplift of the whole mountain massif 75 million years ago. The dramatic views are due to this volcanic activity. Especially of note is the 2,000 m high escarpment extending in a southwest to northeast axis.
There are different types of soils as a result of the difference in geological formation, glaciations, topography, and climate. Humic Andosols are the dominant soil type which is mainly found at an altitude of 3,000 m. The other types of soils are shallow Andosols, Lithosols, and Haplic Phaeozems that are mainly common in the area between 2,500 and 3,500 m. The Simien Mountains are highly eroded as a result of human land use practices and as a result of the topography of the area.
Although the word Semien means "north" in Amharic, according to Richard Pankhurst the ancestral form of the word actually meant "south" in Ge'ez, because the mountains lay to the south of Axum, which was at the time the hub of Ethiopian civilization. But over the following centuries the focus of Ethiopian civilization itself moved to the south, these mountains came to be thought of as lying to the north, and the meaning of the word likewise changed.
The Simiens are remarkable as being one of the few spots in tropical Africa where snow regularly falls. First mentioned in the Monumentum Adulitanum of the 4th century AD (which described them as "inaccessible mountains covered with snow" and where soldiers walked up to their knees in snow), the presence of snow was undeniably witnessed by the 17th century Jesuit priest Jerónimo Lobo. Although the later Scottish traveller James Bruce claims that he had never witnessed snow in the Simien Mountains, the 19th century explorer Henry Salt not only recorded that he saw snow there (on 9 April 1814), but explained the reason for Bruce's failure to see snow in these mountains – Bruce had ventured no further than the foothills of the Simiens.
Despite their ruggedness and altitude, the mountains are dotted with villages linked by tracks.

part of the Simien mountain massif, which is located on the northern limit of the main Ethiopian plateau and includes the highest point in Ethiopia, Ras Dejen. The undulating plateau of the Simien mountains has over millions of years been eroded to form precipitous cliffs and deep gorges of exceptional natural beauty.

Due to its scope and size, the mighty mountain massif of the Simien Mountains is poetically called the ‘roof of Africa’. Ras Dashen, at 4543m, is Ethiopia’s highest peak and its crowning glory.
