Geschichte: The part of the Netherlands where I live has been shaped during the last two ice ages. During the second last ice age many erratic rocks from Sweden were brought here by giant glaciers. During the last ice age, some of those rocks were shaped by the polar winds in the Netherlands which also shaped this granite into a ventifact or wind-abraded rock. You can recognize ventifacts by their two or three faced shape.
Geologie: The location where this rock is from is scattered with small erratic rocks from the South of Sweden. Some of them are wind-abraded by the fierce polar winds that hammered this region some 100.000 - 20.000 years ago. Many of the erratic rocks are granite, like the one here. If you are lucky, you can find a wind-abraded rock yourself.
