The sink lies from the St. Arvans to Rogerstone Grange road, South along the side of a large field.
Description
A small stream sinks near and at the lower end of a small 3 metre deep tree filled depression, where there is a small rock face.
Note - there are some small dry depressions which have been filled in and grassed over, origin uncertain, immediately to the West and several very shallow dolines on the line between this sink and St Arvan's Main Sink
