These cavities in the rocks known by the name of Jettegryter or giants cauldrons are numerous in several parts of the country at various heights above the present level of the sea some in process of formation & are considered as one of the many proofs that the whole of Sweden had once been covered by the sea, from which it is still slowly rising; they are formed by the constant motion caused by the waves of a stone lying loose in a natural hollow of the rock which it changes & deepens until the surfaces of both became polished smooth.

Some are nearly 20 feet deep & 6 feet in diameter & as high as 500 feet above the level of the sea.
