Karakul lake lies within a circular depression interpreted as a meteorite impact crater with a rim diameter of 52 km (32 mi). The impact event is estimated to have occurred about 25 million years ago, or less than 5 million years ago. The Karakul impact structure remained unidentified until it was discovered through studies of imagery taken from space.

Famous quotes containing the words impact and/or crater:
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“Give me a condor’s quill! Give me Vesuvius’ crater for an inkstand!”
—Herman Melville (1819–1891)
