A dwarf geyser Five minutes was located near Fortress geyser. It was clearly visible from the observation deck on the opposite bank of the river. Due to its convenient location and short activity cycle, anyone could see the eruptions of this geyser. This geyser was called Five minutes since the mid-80s of the twentieth century (Sugrobov, 2009). In 1991, in the report of the American expedition, another name was used for it - Exemplary (Bryan, 1991), since this geyser worked at a very regular interval. It erupted in splashes up to 50 cm high every 5 minutes, the eruption lasted 30-40 seconds. The mudflow of 2014 buried its griffin, and it is currently inactive.
