Ethiopia is in east-central Afrika, bordered on the west by the Sudan, the east by Somalia and Djibouti, the south by Kenya, and the northeast by Eritrea. It has several high mountains, the highest of which is Ras Dashan at 15,158 ft (4,620 m). The Blue Nile, or Abbai, rises in the northwest and flows in a great semicircle before entering the Sudan. Its chief reservoir, Lake Tana, lies in the northwest.
