Palsa Mounds

Palsas are rare permafrost mounds of peat. They can be found on Arctic marshlands.

Permafrost can often reach down to dozens of metres. Palsa mounds are formed in the thickest parts where the ice starts to bulge up the peat.

Peat insulates heat, so the permafrost mounds won’t melt in the summer. Palsa mounds can be up to 2000 years old, seven metres high and 20 metres in width. When the mound gets large enough, the peat will tear. This allows heat into the core and the mound will collapse. A pond will take its place.


You can see palsa mounds in Iitto, off Highway 21, 56 km north of Karesuvanto. A nature path with duckboards, will take you right up to the mounds. You can read more about them at starting point.
