I’m currently unable to find much information on the site, it was a jet mine at some point, later converted for water storage.
Possibly for the nearby Gribdale Terrace when the Ayton Bank and Ayton Monument ironstone mines were operational.
The mine is accessed via a tight tunnel with a water pipe down the center.
Inside the mine has concrete dividers storing deep pools of water, and a ladder leading vertically into the woodlands above.
The ladders look very unsafe so its best to back track through the tunnel and look for them in the woods.
Love that last photo. It really needs a speech bubble saying D’OH!
We visited mine October 21st, 2007 The drift appears to be concreted out and in good condition. I am intrigued to know what it was used for, there is also a bricked up tunnel at the end of the drift to the left. As any one got any ideas? Dave.
My understanding is that this was constructed for water treatment by the Fry estate (Cleveland Lodge). It may have been the site of an earlier jet drift but is not connected with the ironstone mines.
I was told that the old jet mine was converted during the first world war years into a small water treatment plant to supply drinking water to the local village. The plant continued to the left of the concrete adit with more settling tanks which has now been flooded and bricked up some years ago.
The original mine had an entrance to the right of the trap-doors and is still open – though requires a good tight crawl to enter.
