Origin of Lukanga Swamp
The nearly circular shape of the main permanent swamp has led to speculation that Lukanga Swamp may be an impact crater (astrobleme) formed by the impact of a meteorite. However research on the ground in 2002 found no evidence of impact shock in rocks of the area, concluding that the Lukanga Swamp is not an astrobleme. In the absence of other research data the origin of the swamp is unknown.

Famous quotes containing the words origin of, origin and/or swamp:
“For, though the origin of most of our words is forgotten, each word was at first a stroke of genius, and obtained currency, because for the moment it symbolized the world to the first speaker and to the hearer. The etymologist finds the deadest word to have been once a brilliant picture.”
—Ralph Waldo Emerson (1803–1882)
“High treason, when it is resistance to tyranny here below, has its origin in, and is first committed by, the power that makes and forever re-creates man.”
—Henry David Thoreau (1817–1862)
“We read that the traveller asked the boy if the swamp before him had a hard bottom. The boy replied that it had. But presently the traveller’s horse sank in up to the girths, and he observed to the boy, “I thought you said that this bog had a hard bottom.” “So it has,” answered the latter, “but you have not got half way to it yet.” So it is with the bogs and quicksands of society; but he is an old boy that knows it.”
—Henry David Thoreau (1817–1862)
