While "arete" is the most common and widely accepted term for a glacial ridge, there aren't really any other common names specifically for a glacial ridge. However, depending on the context, you could use some other terms that describe the specific features of a glacial ridge:

* Knife-edge ridge: This term highlights the sharp, narrow, and often jagged nature of an arete.

* Crest: This term emphasizes the ridge's position as the highest point of a mountain or a chain of mountains.

* Spur: This term is used when the ridge extends from a larger mountain mass, indicating a smaller, less significant ridge.

* Divide: If the ridge separates two distinct drainage basins, this term might be appropriate.

Ultimately, the best term to use depends on the specific context and what feature of the ridge you want to emphasize.
