The geyser Under Pink Cone is a crack about 1 m long and is located in the middle part of the geyserite edifice of the Pink Cone geyser. It was first described by S.I. Naboko in 1951 and named Central Slit (Naboko, 1954). The next description of this geyser, but under the name Central Dwarf, was made in 1960 (Raik, 1963). In 2016, the name Pod Rozovym Konusom (Under Pink Cone) was proposed (Belousov, Belousova, 2017). Geyser activity in 1960: “Before fountaining, water flows for 10 sec. Then water erupts in a powerful inclined stream to a distance of up to 3 m during 1,5 min. Then steaming for 30 sec. We observed 11 cycles, with an average duration of 53 min." (Raik, 1963). The activity of this geyser was quite stable throughout more than 70 years: the period in 1951-1960 was 45-60 min, in 1991-2024 - 35-45 min (Belousov archive). This geyser was not affected by the various natural disasters that occurred in the Geyser Valley.
