English: Lake Meke is a volcanic crater lake composed of two nested lakes located in Konya Province, central Turkey. It is a registered natural monument of the country and a Ramsar site. It was formed by the flooding of the crater of an extinct volcano, which took shape about 4 million years ago when the volcano erupted. About 9,000 years ago, a second eruption formed another volcanic cone inside the lake with a maar. Lake Meke now consists of two lakes with various islets. The volcanic cone island resisted erosion by the harsh weather conditions due to its massive material, and has retained its form for thousands of years.
