A desert plateau region of southern Botswana, eastern Namibia, and western South Africa. Fed by seasonal rains, it has sandy soil and supports grass and other vegetation in all but the extreme southwestern corner.
- The western region, the Kalahari Desert, is mainly arid, with a sandy soil, and is covered in part by dense bush.
- The chief centre in the western Kalahari is Lehututu.
- Crossing the Kalahari Desert, of which Livingstone gave the first detailed account, they reached the lake on the 1st of August 1849.

- The air is unusually dry, owing to the proximity of the Kalahari Desert on the west and to the interception on the east by the Drakensberg of the moisture bearing clouds from the Indian Ocean.
