(The grid reference is an estimate). Water coming out of site 3885 sinks at this point. Heavy rainfall produces a cascade down the hillside that can be seen in a photo of the 0246 area.

In March 2015, 300ml of OBA was put into the sink. Detectors were placed in site 3884 and Jivero 1. The latter proved positive.
