The culvert runs underneath the site of the Grinkle Ironstone mine.
Internally the culvert is on the verge of total collapse, so I really wouldn’t recommend emulating my visit, a previous collapse in 1927 flooded the mine and trapped miners underground.
At the southern entrance of the culvert a large pool of water has backed up due to a collapse, here the tunnel seems to be cut into solid rock.
Interesting post. We walked through this site about a year ago (after visiting the Grinkle fanhouse) and saw the large collapse in what we thought was the old pit yard.
If anyone is interested a nice circular walk can be done in this area taking in the Boulby alum quarries and Grinkle ironstone mine remains, finishing with a pint in the Cod and Lobster at Staithes. Apparently there were considerable remnants of the Boulby ironstone mine standing until the potash mine was built…..
Matthew james would it be possible to email me circular walk of grinkle ironstone mine on the way please.
On this circular walk where do you start from where can you park it would be good finishing at the cod and lobster,how many miles would it be how long this good be a good walk in the summer.
I suppose it would make sense to park at the top of the bank at Staithes, or in the carpark at Cowbar if you don’t want to pay.
Lots of routes you could take, but its a leaast 6 miles.
