Fragility and potential use of the site
Fragility Weathering and natural erosion
Potential use Guided walk
Geodiversity value
Good for links between the bedrock geology and the former exploitation of their minerals. At least one shaft and one adit location can be seen with little risk, if sensible.. Rating: 5.
