This is now a large round area in the field where most of the water from Sima-Cueva del Risco resurges.
During an optical brightener test from site 3884, detectors were placed in the stream near the pasabolo pitch from 13th February 2016 and checked over the next few days in rising and falling flood conditions. The results were consistently negative. The optical brightener came through at the Jivero 1 resurgence after 48 hours. (The full details can be found here.)
The site was visited in March 2016 and described as a muddy hole in a field.
