False 1623-106 Eislufthöhle(106) 1623 1d 106 Numbering cock-up for 76 1623-106 106 was a mistake - the number was accidentally used by CUCC for Eislufthöhle (76) for a while. But we reverted to the Austrian Kataster numbering once the confusion was discovered. So 106 and 76 are two numbers for the same cave. 1623/106/index.htm
