| Location | High Dukerdale, Winton Parish. Westmoreland |
| Civil Parish | Not known |
| Brit. National Grid | NY 81346 05332 |
| Altitude | 518m |
| Geology | Open cast lead workings with shaft mounds on the outcrop of faulted Main Limestone. |
| Record Name | High Dukerdale Scars, eastern side..Open cast lead working, shaft mounds and associated lead bale. |
| Record Description | This lead mine is not identified on 1:25000 OS Map Sheet OL18. The open cast lead mine is visible as a prominent 'hush' or rock cut trench at the upper edge of the sheer limestone cliff or scar which forms the eastern side of High Dukerdale. At the top of the open cast hush are three shaft mounds. Various strings leading from the hush have been worked from the surface.
Most significantly, a circular erosion patch on the southern edge of the 'hush' has fragments of galena lead ore and a small amount of yellow lead slag usually detected as 'splashes' on small fragments of limestone (see photo **). The presence of the slag denotes smelting and the existence of a bale directly associated with the lead mine here.
A careful search revealed the existence of a level driven into the side of the gill directly below the open cast hush. The spoil heap below the hush can be seen on the attached photos.
The lead vein is just one of a series of faults, all of which except this 'hush' are not mineralised, visible in the the face of the Main Limestone Scar at the top edge of High Dukerdale. |
