The legacy of the mining of the district is complex. Now that there is no pumping, mines are flooded to the level of drainage adits, and water escapes through centuries of spoil and rubbish in the workings. Here water, laden with metals (though principally iron) is escaping into the adjacent Porthtowan River. The oxidation of the iron precipitates ochre (iron oxides and hydroxides) as it comes into contact with the air and forms puddles in this unsurfaced car parking area.
