Malysh was a small geyser on the Tramplin (Springboard) Wall at the right bank of the Geysernaya River. The name Malysh was suggested by A.B. and M.G. Belousov, who discovered and described this geyser in 2015. It was located at the lower part (1.3 m above the river level) of steep slope made up of firmly cemented deposits of an ancient landslide (Leonov, 2017). Its channel was a clearly defined oval hole about 10 cm in diameter, which going to a depth of 30 cm at angle of 45 degrees. In 2015, the average period of Malysh activity was 1 hour 45 minutes (Belousov, Belousova, 2020). In 2018, due to the intense erosion of the 2014 collapse deposits, the level of sediments filling Lake Podprudnoye rose sharply, and the channel of Malysh was only 20 cm above the river level, its period became 1 hour 15 minutes, the duration of the fountaining was 20-30 minutes, and the height of the inclined water outbursts 1-2 m. In 2019, water began to pour into the channel. Malysh continued to erupt: the period became 45 minutes, the duration of the eruptions was 10-15 minutes, the height of the water ejections was less than 1 m. In 2020, no signs of Malysh were found.
