   The entrance slope is a pile of festering rubbish. This leads to two circular halls, one of which contains a 7m blind pot. Routes become too low after splitting into two parallel passages. The site was resurveyed in 2021 to obtain the X, Y, Z information and an updated description by Simon Cornhill and Diane Arthurs follows:
   Accessed down the gentle, brambled slope to the entrance of a steeper, large rubbish slope which continued deep into the cave. The way on is at the end of the entrance chamber through the boulders. The way on passes through a large chamber with sloping sides and deep pits. The 2 areas drawn on the survey which looked to continue unknown were small low chambers which closed up. The way on to the North East passages is through a low crawl at the top of the chamber. This continues low for 10m before opening up into a stooping passage. The south west end closes down with large boulders and blocks fallen out of the ceiling. Heading North East the way on is through a squeeze up into the higher level.    The end of the North East passage and the parallel passage end in bouldery breakdown. No draught in the cave. Bones scattered throughout along with guano. A fat rat was spotted on the top of the rubbish heap. Photos taken at various areas in the cave.

   In 1994, both prehistoric and medieval pottery were found in the passage before the first circular hall. These and black markings are described in Smith 1998b and summarised in Ruiz Cobo Jesús and Muñoz Fernández Emilio et al, 2009 and Ruiz Cobo J and Muñoz Fernández E, 2013.
