In flooded ravines, there is almost always broken pillars of terrain that generate on chunk boundaries. This can also happen in ocean caves. To reproduce, use the seed 7596711499214343445 and run the following commands:

Underwater caves no longer exist and have been replaced by aquifiers. Closed as invalid.
Relates to MC-125992, but it happened later (in 1.14 instead of 1.13) so it's not the same bug.
