I admit npe is often a bit approximate, and it may have dried up.
NPE is very approximate. And prone to blackouts from heavy drinking. And

mapped is the stream
continuing straight on to the sea as shown in OSODSV and is very visible in
ESRI. What is not
mapped is the underground channel from the basin to the sea, marked on
OSODSV. What is
mapped doesn't seem to match any of the write-ups I've seen for this
feature whereas OSODSV
does. And even if the mapping is right for the stream, there is no arch
where it has been placed.
Just ATM, I can't recall the right terminology, but these

is a sink hole, which
