False 1623-226b Very similar to 226a but more congested with bunde. Discovered by CUCC, exploration unknown Impossible to verify tag (seen in 2024) ias it is inaccessible due to bunde, and only visible across the hole.

Quite thick bunde (Bing maps extract), some ways through but some impenetrable.
