Updated 20th February 2018

   This is an open resurgence with a reasonable flow. Unfortunately, it becomes too tight 3m in.
A dig, a few metres to the left of the resurgence, gained entry to about 25-30m of hands-and-knees crawling, with a number of branches all ending in pools of water with no way on.

    In early February 2018, over a period with some heavy rain, optical brightener was injected into site 4658, near Garzón. The OBA was not detected here but was detected at site 3282, Santa Juliana. More details and a map can be seen on the hydrology page.
