User:TrulyBlue/Norber Erratics

The Norber Erratics are a collection of sandstone boulders lying on the hillside near Austwick, North Yorkshire. Due to their geological origins they sit on pedestals of rock, above the general level of the surrounding countryside.

Geology
The boulders were transported by glacier from cliffs approximately 1km to the north during the last ice age, around 15 000 years ago. They now lie on carboniferous limestone, which has since been eroded by acidity in rain and soil around the boulders, leaving them higher than the eroded level.
