Nizhne-Semyachikskiye (Lower Semyachik) Hot Springs
North of Semyachiksky Lagoon (8 km from Bolshoy Semyachik Volcano), numerous hot springs are found in the upper reaches and valleys of small creeks at an altitude of 150–160 meters above sea level on a broad area occupied by Ermine birch forests. For ages, these hot springs have been famous for their healing properties, and a health spa was located here in Soviet times.
Hot water springs are found emerge from the upper reaches of a small valley. As the water flows down, it first forms a small hot brook, then slowly becomes a typical mountain creek, abounding in beautiful and warm waterfalls. The brook is called Goryachy Klyuch (Hot Spring).
In spring, while neighboring valleys still slumber beneath huge snowdrifts, the Goryachy Klyuch becomes a natural oasis. Primroses and flittering butterflies can be observed here from mid-March to early April, a fact that at one time awed S.P. Krasheninnikov, the first explorer to visit the Nizhne-Semyachikskiye Klyuchi in 1739.
I.I. Kurenkov collected the first hydrobiological samples here in 1957. The temperature of the springs reaches 490°С, and water discharge is equal to 70 liters per second. A beautiful three-meter waterfall graces the upper reaches of the brook. Hydro-carbonic-sulfate and calcium-magnesia-potassium compounds are dissolved in the water. For ages, these hot springs have been famous for their healing properties, and a health spa was located here in Soviet times.
Warm springs also feed the Tyoply (Warm) Brook and Tyoploye (Warm) Lake in the Semyachiksky Lagoon watershed.
