The border follows the Caledon River, the drainage divide of the Drakensberg mountains, the Tele River, the Orange River, the Makhaleng River, and a series of hills joining the Makhaleng back to the Caledon.

Geology of Lesotho Geology of Lesotho The geology of Lesotho is built on ancient crystalline basement rock up to 3.6 billion years old, belonging to the Kaapvaal Craton, a section of stable primordial crust.

The country is notable for large fossil deposits and intense erosion due to high rainfall and a rare case of southern African glaciation during the last ice age. Lesotho has extensive diamonds and other natural resources and has the highest concentration of kimberlite pipes anywhere in the world. Lesotho shares many commonalities
