Highlands

Madagascar’s central highlands, which range from 800 to 1,800 m (2,600 to 5,900 ft) in altitude, contain a wide variety of topographies: rounded and eroded hills, massive granite outcrops, extinct volcanoes, eroded peneplains, and alluvial plains and marshes, which have been converted into irrigated rice fields.

The central highlands extend from the Tsaratanana Massif in the north to the Ivakoany Massif in the south. They are defined rather clearly by the escarpments along the east coast, and they slope gently to the west coast.

The location of these east coast escarpments can be identified in the image as the line where the reddish brown color of the highlands changes abruptly to dark green. The gradual slope to the west, on the other hand, is indicated by the rivers flowing downwards into the Mozambique Channel.
