Summary of site:
A 20m shaft drops on to a 12m slope leading down to a still lake, 36m long. Near the end of the lake there is a small passage which gives access to a substantial passage ending in a chamber. The flow of a major stream, presumed to be the Owenbrean, can be heard from here. A tight crawl from this section of the cave connects with Bruce’s Pot.
Only one dive into the depths of the lake has been attempted. After 8m of descent it opened out into a large, cavernous space that was not explored further.
