Giant's kettle that was made during the melting of the glacier after the ice age.
When the massive glacier, which lay over large parts of northern Europe, was melting away, large rivers was formed under the melting glacier.
These large rivers between the bedrock and the glacier some places in these large rivers large whirlpools were made. Larger and smaller stones crumbling around these currents will over time make such giant's kettle. These are cylindrically shaped with vertical walls. Typically, the Giant's kettle is higher than they are wide.
Along the mountainsides of the fjords in the Western part of Norway, there are many Giant's kettles.
The Giant's kettles on these pictures are from the mountainside at Fjæra in Åkrafjorden.
