Image Caption: Dakar exit
The continental exit best photographed from Shuttle is the one centered on Africa's west coast. Here the well-known Dakar cape (right) appears with almost complete loss of detail. Further north (top left) the Mauritania's coast disappears completely under dust. Dust can be mobilized and kept aloft for hundreds of kilometers, typically from the Chad basin--before even reaching Africa's west coast. Here the dust passes out over the Atlantic where most falls near the continent (dust thicknesses on the sea bottom become thinner away from the coast).
