the.com/sea stack
A cliff that lost an argument with the ocean but kept standing anyway.
means A tall column of rock standing alone in the sea, left behind after waves cut it off from the cliff it used to be part of.
from Straightforward compound: 'sea' plus 'stack,' which has long meant a pillar-like heap or column (as in a haystack or chimney stack). Geologists borrowed the everyday word 'stack' for these isolated rock towers because they look like something piled or standing upright — no hidden backstory, just a plain description that stuck.
