Straight drive to blind, about 400feet long with a small recess about half way along. No significant mineralisation. A few iron pipe hangers in the wall are the only real presence of iron. Entrance has been partially dammed by the farmer to provide drinking water for livestock.
Nothing known. Most likely an iron trial as there were several in the area. Not shown on Ordnance Survey maps until the 1960s.
