Glacial erratics on Stronsay
In April 2008 Brown and Hall collected exotic stones from beaches and till faces at several sites in southern Stronsay in order to better understand the range of erratic material present on the island. The captions refer to provisional rock descriptions made at the time of photographing them in April 2008. These descriptions were made without close examination which remains to be done to confirm rock type. Let us know if you spot errors or indicator rocks.
