Show on mapAn entrance to extensive jet workings opened beside the footpath during forestry work in 2002 and was subsequently explored by the Moldywarps Speleo Group and Scarborough Cave Club. Nearly 1000m of passages were discovered, their investigation and mapping being covered in much details in Cleveland Industrial Archeology No. 30.
The entrance is now gated and locked, although looking down into an adjacent small collapse gives a good idea of the narrow and fragile passages through the shale.
The area of surrounding woodland is littered with collapses relating to the workings, some of the larger ones very dangerous due to ground cover, depth and collapsing sides.
In fields to the south west, three parallel collapses are visible and a large shale tip still scars the hillside. These show up particularly well if you click the “Show On Map” link at the top of this post.
Great article, we never knew this was so close! We’ve been down there a few times but could not find the gate itself, we did find three holes in the ground though, clearly marked with wooden fences and barbed wire.
Could you give any hints to where the gate itself could be? We’ve searched the entire area surrounding the known holes.
overgrown now but its near the top path
