Ancient Lake
An ancient lake is a lake that carried water without interruption for more than one million years. The vast majority of lakes, including very large ones such as the Great Lakes, are of much more recent origin. The short life of most of lakes is due to continued sedimentation by their tributaries, which typically leads to complete siltation after several thousand years. In contrast, the longevity of ancient lakes can mostly be attributed to geological factors, such as plate tectonics, which can counter siltation.

Famous quotes containing the words ancient and/or lake:
“Men must speak English who can write Sanskrit; they must speak a modern language who write, perchance, an ancient and universal one.”
—Henry David Thoreau (1817–1862)
“They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head.”
—Henry David Thoreau (1817–1862)
