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.
