Jumble Hole Clough - Hebden Bridge

Jumble Hole Clough forms the old boundary between Yorkshire and Lancashire. Its former name was Blackshaw Clough. It is a steep sided wooded valley formed by a fast flowing stream that flows into the River Calder.
Underneath the natural looking stream and the vegetation, there is a marvel of 18th century water engineering - weirs, mill dams, goits, sluices etc. These were all constructed to ensure power for four mills built down the valley- reusing the same water for all four mills!
The mills have all gone, but the stream remains - flowing on and on :-)
