The Seyðishólar is a group of craters north of Kerið in the Grímsnes district in southern Iceland .
Iceland's youngest volcanic system
The cinder cones are 5000–6000 years old. The highest crater is the twin crater Seyðishóll (214 m). Its rock is very ferrous, which u. a. recognizes in the gravel pit, which is used to extract building material. There is a mobile phone and TV transmitter on the southern Zwillingsberg.
The craters lie over a small magma chamber of their own . This is the Grímsnes volcanic system , the youngest active volcanic system in Iceland. a. Kerið crater belongs to the same as the hot springs at the foot of Búrfell í Grímsnesi . It does not yet have its own central volcano.
The largest lava field in the area, the so-called Grímsneshraun , was produced by them.
Summer houses
There are large colonies of summer houses near the craters.
