A dwarf geyser Norka (Small Burrow) located on the Piip wall of dwarf geysers, opposite to the geyser Bolshoy (B.I. Piip is a famous volcanologist, the first director of the Institute of Volcanology). It was described only once: in 1991 by members of the Geyser Observation and Study Association (GOSA) (Bryan, 1991). It erupted from a small gryphon, similar to a crack, from which geyserite deposits descended down the wall. Eruptions were repeated every 5 minutes. Their duration was 10-20 seconds, and the height was up to 1 m. In 2007, the location of the geyser was flooded, and in 2014 it was covered with a multi-meter layer of mudflow deposits.
