During the 2nd World War the Burbage Basin, below Burbage Edge was used as a military training area and there is still plenty of evidence of that today.  You don’t have to look very hard to find huge boulders covered in bullet holes and marks from mortar shells.  Usually the holes in the rocks are just one one side as they were used as targets whilst practicing attacking uphill positions.

This gritstone boulder is just off the main ‘Sheffield Country Way’ path through the valley, but there are lots more spread over a wide area.
