Geography of Lesotho - Physical Geography

Physical Geography

Lesotho can be roughly divided into three geographic regions: the lowlands, following the southern banks of the Caledon River, and in the Senqu river valley; the highlands formed by the Drakensberg and Maloti mountain ranges in the east and central parts of the country; and the foothills that form a divide between the lowlands and the highlands. The lowest elevation in the country is at the junction of the Makhaleng and Orange (Senqu) rivers (at the South African border), which at 1,400 metres (4,593 ft) is the highest lowest point of any country. Lesotho is the only independent state in the world that lies entirely above 1,000 metres (3,281 ft) in elevation. The highest point is the peak of the Thabana Ntlenyana mountain, which reaches an elevation of 3,482 metres (11,424 ft). Over 80% of Lesotho lies above 1,800 metres (5,906 ft).

Even though very little of Lesotho is covered in water, the rivers that run across the country are an important part of Lesotho's economy. Much of the country's export income comes from water, and much of its power comes from hydroelectricity. The Orange River rises in the Drakensberg mountains in northeastern Lesotho and flows across the entire length of the country before exiting to South Africa at the Mohale's Hoek District in the southwest. The Caledon River marks the northwestern part of the border with South Africa. Other rivers include the Malibamatso, Matsoku and Senqunyane.

The bedrock of Lesotho belongs to the Karoo Supergroup, consisting mostly of shale and sandstone. Peatlands can be found in the highlands of Lesotho, most extensively in the mountainous escarpment near the country's eastern border. The summit of Thabana Ntlenyana is partially encircled by bogs.
