Another name for the Cleveland Dyke is the Armathwaite-Cleveland Dyke. The dyke outcrops in the Eden Valley at Armathwaite where it forms a weir across the river.
This natural weir was exploited in the past by a watermill on the Armathwaite side of the river and a salmon fishery on the other. The mill site is currently being redeveloped, all thats left of the fishery is a ruined building and a large keep pool.
The dyke was quarried on a small scale locally
Heading south on the A6 I noticed this.
