Ethiopian Highlands
The Ethiopian Highlands is a rugged mass of mountains in Ethiopia, situated in the Horn region in Northeast Africa. It forms the largest continuous area of its altitude in the continent, with little of its surface falling below 1500 m (4,921 ft), while the summits reach heights of up to 4550 m (14,928 ft). It is sometimes called the Roof of Africa due to its height and large area. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea.
History
In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval early modern state, whence the coffee plant was exported to the Arabian peninsula. The land where this former kingdom lay is mountainous with stretches of forest. The land is very fertile, capable of three harvests a year. The term "coffee" derives from the Arabic qahwah ( قهوة), and is traced to Kaffa.
Physical geography
The Highlands are divided into northwestern and southeastern portions by the Main Ethiopian Rift, which contains a number of salt lakes. The northwestern portion, which covers the Tigray and Amhara Regions, includes the Semien Mountains, part of which has been designated a national park. Its highest peak, Ras Dashan (4550 m), is the highest peak in Ethiopia. Lake Tana, the source of the Blue Nile, also lies in the northwestern portion of the Ethiopian Highlands.
