Geological History
Tens of thousands of years ago, the Azov Sea was much larger and covered the delta of the Kuban River. Deposition of silt by the Kuban gradually pushed out the sea and shaped the delta with numerous limans and shallow estuaries. Frequent eruptions of the mud volcanoes contributed to this deposition process. There are about 25 mud volcanoes in the area and some are still active.

Famous quotes containing the words geological and/or history:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
“Anyone who is practically acquainted with scientific work is aware that those who refuse to go beyond fact rarely get as far as fact; and anyone who has studied the history of science knows that almost every great step therein has been made by the “anticipation of Nature.””
—Thomas Henry Huxley (1825–95)
