A spacious, dry entrance opens up to over 2000m of easy walking passage of railway tunnel dimensions. This is an ancient abandoned resurgence cave which heads, joint-controlled, into the hillside. The hard earth floor is covered in places in nitrate pits, some of which are 5m deep. The sheer volume of the workings suggests that this process spanned many years, but other than the disturbed floor, and remnants of mud walled settling tanks, no artefacts survive.
Here and there drips have produced deposits of flowstone, especially towards the far end. Exploration terminated at a low, too tight, section, possibly quite close to the surface, because it was occupied by a very active bat population.
