False False Sattelhöhle 1624 137 1624-137 caves-1624/137/137.svx ARGE or VfHO cave. 3 adjacent entrances.

See 1624-all-caves.pdf This is (probably) an ARGE or VfHO cave where we may only have the survex file.
But do check the scanned PDFs especially for caves in kataster area 1626.
If there is a 'Messteam' or 'Zeichner' listed, then it is probably ARGE.
