The main car park overlooking Cow Green Reservoir is situated close to the former workings of West Cowgreen Mines. The mines were initially worked for Galena (lead ore) with large amounts of Barytes occurring as a gangue mineral. When a market for Barytes was found the mines were then reworked and extended for this mineral which was present in vast quantities. The veins occupied the lowest beds of the Carboniferous including the Melmerby Scar Limestone (and the Whin Sill).
We shall explore some of the surface exposures of the mineral veins at West Cowgreen and look at old mine buildings at Dubby Sike mine, to the west. The track to the dam of the reservoir runs past further mine workings, some small limestone quarries and close by the unusual ‘sugar limestone’. The upper surface of the Whin Sill is exposed in a stream and, below the dam, Cauldron Snout cascades down through the full thickness of the Whin Sill. This is truly a special place, not only for geology.
