Two paths at the Skallgrusbank in Sillviks Nature Reserve – the one through the white chalk soil, the other a dissipating contrail. With a little imagination you might see one as a continuation of the other.
Skallgrusbank means “shell gravel bank”, so it’s not really chalk (which is an unusual rock here abouts). It’s actually the remnants of millions of small shellfish that lived and died here about 10,000 years ago when this was a shallow bay of the sea. The land rose and the shell gravel was never compressed into chalk. Silviks Nature Reserve preserves an early industrial landscape – the shell gravel was mined here in the late 1800s as an ingredient in fertiliser and construction.
