Kettle holes were formed when blocks of ice broke off from a retreating glacier and became embedded in the moraine. Deep hollows were left when the ice melted. Today most kettle holes are lakes, but Djupa hålet is completely dry and is 46 metres deep.
In this region, the ice sheet began to melt about 10,000 years ago. The ice front remained stationary for a long time in the region around Lidetorpsmon. Large amounts of rock material at the surface were washed downwards by vertical fluvioglacial streams. The sub-glacial streams emerged at the front of the ice and flowed into the sea. The sediment became sorted, with the coarsest material sinking to the bottom near the edge of the ice while the finer, lighter material was washed further away before being deposited. A marked path leads through the area, and there are two picnic spots.
How to get there
Lidetorpsmon is situated on road 243 halfway between Degerfors and Åtorp. There is a signpost on the road.
