sentences:  The gelada baboon and the caracal, a cat, also occur within the Simien Mountains
  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 Aksum, which was at the time the center of Ethiopian civilization.But as over the following centuries the center 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 Semiens are remarkable as being one of the few spots in 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.
