the.com/ice shelf
A glacier that forgot where the land ended and kept walking.
means A thick, floating slab of ice attached to a coastline, formed where glaciers or ice sheets flow out onto the sea and keep spreading rather than breaking off.
from Straightforward compound English: 'ice' plus 'shelf,' the second word borrowed from the same sense used for rock shelves or continental shelves — a flat, projecting ledge. The phrase emerged in 19th and 20th-century polar exploration and glaciology as explorers and scientists needed plain language for these vast ledges of ice jutting off Antarctica and the Arctic. No hidden story here: the name is purely descriptive, coined by people staring at something literally shelf-shaped and calling it what they saw.
