The cave is in a 20m high cliff face with bushes and has been marked M22 by SEAD. The entrance is 5 x 8m. A walking size passage lowers to a draughting tube which has been dug to lowish passage with straws and stal.

A sediment sample has been taken.

In the summer of 2003, the draughting eye-hole at the end of the 94 extension was opened up and a further extension made at essentially the same level. The extensions, by members of the Derbyshire Caving Club, are described on the DCC web site and summarised here.
The extension consists of a continuation of the main passage which is about 5 metres diameter and phreatic in origins. This has been filled with mud and calcite in various phases and in parts only the top section is accessible, hence the dig and two squeezes dug through. However, in the extension, two separate inlets have washed out the infill and left sizeable chambers. The passage continues after the second chamber but is filled to the roof and has no draught. The first chamber has a second inlet and both get too narrow. The best prospect is the outlet in the first chamber where the draft emerges. This has been dug briefly and a return visit would be worthwhile, especially as it hints at a deeper level for the cave. Between the two chambers is a low passage on two levels divided by a false floor. Above this is another inlet which has been explored for a short distance.
In the final chamber, the way on is blocked to the roof but there is also an aven and hole in the floor which were looked at in 2004. Work continues, but has the final pot been descended?

At Whit 2007 a side passage on the right just beyond the DCC memorial was opened up. This leads back to the cliff face but is blocked with a (possibly ancient) dry stone wall. There are bones on both sides of the wall and a possible continuation running parallel to the cliff after what appears to be an easy dig. (There were also a lot of fleas). In 2012, the "oval slot", with larger passage beyond, was found to be too tight but may be possible for a "youth with attitude".

Various Bronze and Iron Age items, including pottery, have been found in the entrance chamber. Details have yet to be published (Ruiz Cobo Jesús et al, 2008, p228).

In 2012, probable wild boar bones and teeth were identified at the start of the extensions and other bones noticed in the earlier sections including small carnivores and a large bird.
