Hi Pilgrim,thanks for that info,a knew aboot the opencast,but nivvor hord owt aboot thi artifacts found there!!
A can mind the notice aboot thi old mine shafts in Hartford woods.
There's an old mine addit alang the Free wood on the Blyth side "top path",and the rails were still visible amang the tree roots and overgrowth.
We kids used to poke lang sticks inti the orange waata wat was lying aal aroond the entrance ti thi drift...pure orange it was....Ferric Oxide?[from the Iron-stone strata]....wud it have been from the old ironworks mining the ironstone maybe....or older?
The waata at Choppington High Pit was very high in iron content similar to that in the woods.
