<underground_description>An east-west rift with two obvious points of descent. The more easterly is about 6m deep and can be seen to end in a chamber. The more westerly is a 15m pitch, with a window communicating with the east hole. At base are boulders and a climb down. A crawl leads to an inlet where water appears and sinks into an impenetrable slot with very sharp rock. </underground_description>
