This is found by going northwards from the lower mine adit across an old wall with the lowest outcrop to the left. The entrance is to the left at the top of a scree slope. The entrance cannot be seen until approached closely. The 3' x 3' entrance appears to have had a trench dug out fairly recently. From the entrance, the passage is 8' high and about 3-4' wide.
Some nice ferns grow inside the entrance.
After about 30', the passage lowers to 2.5' before entering a small chamber with digging implements. This cave is presumed to be Lynx Cave which is an archaeological site. I couldn't find this one. It is supposed to be 100m further north from Cave 1 at the top of a small scree slope. It is apparently a low crawl.
