Hundreds of thousands of years from the depths of the Caucasus come to the surface of the hot springs. In a number of cases, this is accompanied by a powerful gushing, like geysers, but mineral waters are a manifestation of non-active volcanism, and extinct. It is the synthesis of atmospheric precipitation and carbon dioxide: the first through the fractured surface of the constituent lavas penetrate to the deep warm layers, blur the minerals and, even in the form of a new natural formation, go out. Since ancient times such springs are also called “jermuk”. Since ancient times, people know their healing properties, as evidenced not only by folklore, but also by the presence of abandoned reservoirs-bathing.
Several hundred similar sources exist on the territory of the Armenian highland, especially in its Caucasian part. Often these are entire complexes, and one of them is Jermuk, located at absolute altitudes of 1,700-2,200 meters. The Jermuk waterfall is the second highest waterfall in Armenia after the Kasakh waterfall. The height of the waterfall is 68 meters, it is in Armenia, in the province of Vayots Dzor.
