The term "ice front" can be used to describe the leading edge of a glacier or ice sheet that extends into a body of water, but there are several synonyms that can also be used to convey a similar meaning. Some alternative phrases for ice front include glacial terminus, ice margin, ice face, and glacier snout. "Terminus" is derived from the Latin word meaning "boundary," and is often used to describe the end point of a physical feature. "Margin" is another fitting term, as it can refer to the edge or border of something. "Face" and "snout" both emphasize the visual aspect of the ice front and its shape. Ultimately, the choice of synonym will depend on the context and intended emphasis of the description.
