A view of the former Hummersea alum workings, almost disappearing under the eroded surface.

The stone outlines are the remains of liquor channels used to move the resultant liquids to the settling tanks.

Thanks to Eric Johnson for the photographs and information.

I know, it’s just a photograph of some cliffs, possibly Boulby Cliffs, but that is worked stone and the photographer knew it (and I bet he knew more about it than we do!), so the big questions are 1) Where is it and 2) What was it?

I’m fascinated!

John Hannah answered question 1 – it is Boulby Cliffs and it is adjacent to the Alum workings mentioned in an earlier post.  Eric Johnson answered question 1 and question 2, because he took the photo!  Eric you must have been barmy getting that close to the edge! – thanks for the answer though, rodders.
