Volcanic Springs

Geysers, Hot Springs,
Mud Pots, and Fumaroles

Þeistareykir, Hillside Group

The northern slope of Mt. Bæjarfjall is covered over and over with geothermal features in bright colors. Starting from the valley floor in the north you first come across a small creek tinted in bright yellow, orange and red shades by pinhole fumaroles in the walls. This is what Icelanders call a Rauðþúfur (red puff).

On the floor south of the creek two small mud pots stand out, featuring amazing volcano shapes.

All hot springs of this group discharge muddy gray water, some are splashing a little, others are quiet. The next three pictures show the largest of them, which particularly resembles a world map.

Last but not least some more pinhole fumaroles are part of the Hillside Group. In Iceland this kind of fumarole is called Brennisteinsþúfur (sulfur puff). Two typical examples are shown below.
