The first geographic informations about the cave were given in the 1960s. At first, the cave was called Keck-Tash, which in Altai language means “blue stone” (the color of Cambrian limestone). Speleologists of Altai later decided to call it “Ecological Cave”. The cave is a complex system made up of 10 caves and shafts as well as inclined corridors with different levels with ground variations of 3 to 4 meters. The main chamber is Mrachni. It covers an area of 200 sq-m and is 25 to 35 meters high.
