| A manchester caver is trying to achieve the potholer's ultimate challenge by going deeper underground than anyone has been before. |
| Both types of devices allow the caver to control their descent by applying friction to the rope that is threaded through them. |
| But to see it you need to have the eyes of a caver as it travels under 400 m of limestone. |
| Crawlways run as straight as dark directional lines, meeting others in mazy routes that confuse even the most observant caver. |
| A caving rescue was actived during Easter 98 week-end to come back up, an exhausted caver from the lower part of the pitch. |
| The experienced caver and climber died a few hours later while potholing, plunging 70 feet to her death. |
