The geothrmal field around the
geyser, which is the world wide eponym of all spring sources, is about
8000 years. After the earthquake in 1630 the geyser started with its main
eruptions. Until to the end of the 19th century the geyser was spattering
about 60 meters. In 1916 the spattering stopped at all and soap was the one
solution to keep this geyser active By adding 40 kg of soap the activity
was reanimated, until the natur conservancy stopped that nonsense because of
the land pollution. Fortunately this geyser has an reliable neighbor:
Strokkur, the butter churn. This name was given because its shaft is
constricting like a butter churn.
Strokkur, also named "butter churn".
With its steady eruptions between 1-10 meters this geyser is the most
active on this island.

Thermal source Blesi (Blesse)
near the geyser. The thermal basin is colorless and filled up with
boiling water. The other one which is lower situated is 40 C° 'cold'
and has as the result of the interaction with the precipitating
silicic acid and the air a shining azure color.
