This short focal-length astronaut photograph shows the entire Okavango “delta,” a swampland known in southern Africa as the “Jewel of the Kalahari Desert.” This enormous, pristine wetland almost miraculously appears in a desert where surface water is typically non-existent. The water comes from the Okavango River, which rises in the high-rainfall zone of southern Angola, hundreds of kilometers to the northwest. The dark-green forested floodplain is about 10 kilmeters (6 miles) wide where it enters the view (image left). The Okavango then enters a rift basin, which allows the river to spread out and form the wetland. The width of the rift determines the dimensions of the delta—150 kilometers (90 miles) from the apex to the downstream margin (image right). The apex fault is difficult to discern, but two fault lines define the downstream margin; the faults appear as linear st...
