This moorland trackway is one of the great droveways over the Cheviots between England and Scotland. It linked Morpeth with Kelso and crossed the border at Outer Cock Law. Since the Anglo-Saxon times cattle have been driven along these roadways to markets in England. One name for the road is Ermspeth, which means ..eagles' path.. . This name comes from Old English and shows how old the track may be. More recently the track became known as Clennel Street.
