The small stream that runs down the valley to the sea at Trevellas Coombe near St Agnes.
As you can see this area was once the centre of a mining operation. Known as the Blue Hills Mine this ran up to the 1900s.
These days the only tin retrieved here is from this stream. The Blue Hills Tin Streams is a small family run operation which collects naturally occurring tin from the stream and turns it into jewellery.
