Area position

The entrance is a 1.5m by 1m opening at the top of the grassy bank 35m to the west of the top entrance of Cueva Espada. This was explored at Easter 2013.
A sloping entrance pitch of 10m drops into a short section of fair sized stream passage. Upstream the passage chokes after about 25m, while downstream the stream immediately sinks near a too tight sump pool. The passage continues and splits. To the right is a cobbly passage which gets too tight, to the left rises to a choke with surface debris, while a muddy crawl straight ahead ends after about 10m at pools.
The source and destination of the stream, which was active in relatively wet conditions, is uncertain, there being several sinks in the immediate area, and it presumably joins the stream in Cueva Espada at some point.
