Area Of Disused Shafts

An area of multiple collapsed, partially filled in, or covered, vertical (or near vertical) shaft entrances related to former mining activity.

Area Of Former Mineral Workings

An area of land with a collection of different features indicating former mining activity. This is for areas where there is clear evidence from the terrain of mining activity, but the features cannot be precisely captured and identified because of their age. Examples include areas of former tin or lead mining where a mix of disused shafts, hushes (channels washed out to expose minerals), dams, drifts, levels, spoil heaps and other unidentifiable features combine to form a distinctive landscape, but most or all of the individual features appear too eroded to be captured individually.
