Why “icefall” is a great word
A steep, fractured, and rapidly flowing section of a glacier, resembling a frozen waterfall. From the roots *ice* and *fall*, modelled after *waterfall*, the term was first recorded in 1810–20. Unlike a 'glacier,' which denotes the entire, slow-moving river of ice, or a 'serac,' which names a single, treacherous tower, an icefall is the violent process of the whole structure tearing itself apart under gravity. It is a labyrinth of yawning blue crevasses, a cacophony of grinding and shattering, and a landscape perpetually collapsing in slow, crystalline motion—a stark monument to the fact that even solidity, under sufficient pressure, must eventually fracture and flow.
