Burlyashchy (Bubbling) is the largest geyser in the upper part of the Valley of Geysers. Until 2014, it was located on the slope of the right bank of the Geysernaya River 20 m above the water level. Its griffin was located in a depression 5 x 10 m. It was originally described by Ustinova (1946): “A small geyser on the right bank approximately 1 km above Velikan throws out a little water to a height of about 3 m.” The name “Burlyashchy” was first encountered in an article by V.N. Vinogradov in 1964. In August 1950, B.I. Piip briefly visited the Valley of Geysers and probably saw the eruption of Burlyashchiy: “The water continued to boil quietly for 5-10 minutes. Then the boiling became stronger, the water began to flow down the slope, and finally everything began to bubble, and the water was thrown to a height of about 1 m. Such activity continued for about 10 minutes, then everything quickly weakened, the water in the depression disappeared, and the bubbling began to be heard from the depths." Description of its activity at the summer of 1961: “Fountaining during 11 minutes, the height of the fountain is 1.5 m, steaming for 26 minutes, the period is 56-62 minutes” (Sugrobova's archive). In the mid-to-late 60s, Burlyashchiy began to operate in a pulsating mode with alternating increases and decreases in activity. In 2012, the fountaining height was up to 1-2 m (data from the Belousovs). In 2014, Burlyashchiy was buried under landslide deposits, but continues to operate as a pulsating spring.
