The Geysers Valley was discovered only in 1941, by a Russian woman scientist named Ustinovich. Since then the valley, northeast of Petropavlovsk-Kamchatskiy, has been protected as a zapovednik, or national preserve. The valley is about two kilometers long, with many different geysers. Every geyser has its history and its name. The biggest are called Giant, Jubilee and Malahitoviy.
Geysers are a manifestation of volcanic activity.
Between volcanic eruptions, volcanic processes are manifested in gas and steam eruptions, in the appearance of hot springs and in geysers. All these phenomena are known as geothermal activity. The effect, in expert opinion, is no less than that of volcanic activity itself. Geysers cause great changes in geological structures, wash and carry away minerals and even form new ore fields. At Geyser Valley there is a great variety of geothermal activity, including hot springs and lakes, mud kettles and mini-volcanoes, pulsing sources and erupting water fountains.
