West Wheal Buller


Also known as West Wheal Buller.

Access to the dump is best obtained via the lane that runs along the top of Basset mine. Near to the riding school gate, there is a small side gate in the hedge giving access to a field. The dump is reached by going through this gate and climbing the slope before branching off left. The dump is visible and a rarely used footpath leads to it.
The site is used for clay pigeon shooting, mostly on a Sunday, and the entire area is littered by the shattered remains of the clays.
Anyone with a Geiger counter will soon discover several 'hot spots' where the background radiation is considerably higher than normal. In places the soil is radioactive, and some of the rocks and stones contain uranium minerals, mostly uraninite.
