Where are the Ethiopian highlands located?

Ethiopian Highlands,

It is also the rugged plateau region of Africa, covering about two thirds of Ethiopia. It is divided into two massifs by the Great Rift Valley; the Amhara, or Ethiopian Plateau, is the larger of the two. The region, which slopes away from either side of the Great Rift Valley, is composed of a series of mountains and valleys; Ras Dashen (15,158 ft/4,620 m), Ethiopia's highest peak, is there.
