| Summary of site: |
| Except for the active stream entering Polliniska, it is the least important component of the Polliniska – Pollnatagha – Pollprughlisk triumvirate. The stream flowing over the border with the Republic of Ireland from the south enters Polliniska by a 6m by 3m opening, 10m deep. At the bottom of this shaft the stream flows laterally and enters the main Pollnatagha shaft about 20m down. |
