A possible overflow sink beyond the sink, site 4882.
   Other sites probably associated with this are 4883 and the resurgence, site 4885. Although there is only 170m straight line distance between the sink and the probable resurgence, there is potential for inlets entering from under the steep valley sides so the "system" may well warrant further investigation.
