That's right, it's High Skears Mine. Interestingly, the London Lead Co. plans don't give the level there a name, and Marlbeck is marked as 'Old Marlbeck'. From those same plans (the then unnamed) High Skears Mine isn't shown as connecting with Marlbeck. I don't know if any modern explorers have found connections between High Skears and Marlbeck (you'd have to be pretty thin to get in through the hole left for the water at High Skears!). However, (Old) Marlbeck is shown with a drive north to connecting in to the workings at Lodgesike at a lower horizon.Thanks for this you have cleared something up. So the one with the sheep pens outside is High Skears and does not connect with Marlbeck,.
Others would be better placed to confirm that for you Roy. Again the plans I've got show Firestone communicating with the Coldberry levels. I know some of the Durham Dales Mining Society guys did some work within the levels back in the 90's to reopen a number of collapses and wrote up their work and findings in their Firestone publication, but I'm not sure what through trips are possible today.So the Skears through trip ( I have never been in for some reason) is from the Firestone down and out through Low Skears.
