   A steep-sided valley broadens out and the small stream sinks against the side of the hill. A couple of small holes at sinks level have been investigated but water appears to filter away in the cave floor. There are rifts in the jungle above that need investigation.
   In April 2017, the site was found to be very overgrown. Six months later, the stream above was investigated. It splits into several discrete feeders, one of which ends at the small resurgence, site 4605.

   In October 2017, an inconclusive water trace was carried out along with some collection of water chemistry data.
   On 27th February, 2018 optical brightening agent was injected into this site and detected at site 3282 on 1st March.

   The site was visited in October 2018 when water conditions were low. It was possible to enter the sink and exit 5m away in the same scar. The next cave along has a visual connection with a fourth cave. All these caves are choked with farm and domestic rubbish and have a total length of about 25m.
