Minewater first appeared in Saltburn Gill on 18 May 1999, since then the beck has been stained with ochre, this occured 35 years after Longacres mine actually closed so many think its probably due to the construction of the Skelton – Brotton bypass between Longacres and this location causing some movement underground.
This problem also exposed a legal loophole whereby neither the current landowners nor former operators can be held responsible. The coal authority is also not currently responsible for old metal mines.
An extrememly informative article on the subject can be found in a recent issue of Geoscientist.
The interesting overlay of the workings is to be found on the informations boards by the beach.
