The pulsating boiling spring Dvoynoy (Double) is located at the lower left corner of Vitrazh. It was first described and named by T.I. Ustinova. Its geyserite structure is about 6 meters high and consists of two griffins (upper and lower), which look like cracks of impressive size. The geyserite structure above the upper crack is called Sedlo, above the lower one - Stremya. "From the upper crack, water partially enters the lower one, and partially pours out onto the slope. They do not have a period of violent activity, water emissions are irregular" (Ustinova, 1955). "Inside the structure there are 2 vents that act independently of each other" (Bryan, 1991). In 2014, the upper vent did not work (observations of Belousov). In 2024, unsystematic splashes of water from the upper vent were observed for 1-5 seconds to a height of up to 0.5 m. The events of 2007 and 2014 did not affect the Dvoynoy.
