STS106-713-55 Broad North-trending folds of the Cedarburg range, South Africa, formed during the assembly of the supercontinent Gondwana, about 230 million years ago. The West-trending Karroo ranges formed a little later, the south ends of the older ranges were refolded during that episode.

STS106-713-60 The West-trending folds of the Karroo ranges were formed ~228 million years ago. Dips of rock layers in the folds, as well as fractures that localize stream courses, are readily observed here.

STS106-713-37 Okavango River delta and Lake Ngami, northern Botswana. Very heavy rains in late 1999 and early 2000 have created a wet Lake Ngami.

STS51I-33-54 Okavango River delta and normally dry Lake Ngami, northern Botswana, dry in 1985.

STS106-715-51 Northern Namibia under widespread smoke pall, probably as a result of greatly increased biomass growth--which in turnresulted from very heavy rains in the wet season of late 1999-early 2000.

STS41D-37-67 Northern Namibia under more usual smoke-free skies--September 1984.

STS106-716-69 Southern Mozambique under widespread smoke pall.

STS106-716-27 Lake Eyre, South Australia, with ~3000 km2 of ephemeral lake surface; Lake Eyre responds to El Niño events by drying up. In the September, 2000 view the lake is about half full; it was notably fuller in July, 1997 but entirely dry in April, 1998. Lake Eyre time series (STS094-748-083 of July 1997, STS089-717-055 of January 1998, and NASA7-714-014 of April 1998).

STS094-748-83 Lake Eyre time series: STS094-748-083 of July 1997, STS089-717-055 of January 1998, and NASA7-714-014 of April 1998.

STS089-717-55 Lake Eyre time series: STS094-748-083 of July 1997, STS089-717-055 of January 1998, and NASA7-714-014 of April 1998.
