Meltwater stream plunging down a deep pot-hole or 'glacial mill' in the surface of the Solheimajokull Glacier, Southern Iceland

---

Summer meltwater on the surface of a glacier may be channelled into a crevasse or vertical tension crack. A combination of melting and the scouring action of sand and stones in transport cuts a deep pot-hole (termed a 'glacial mill' or 'moulin') in the surface of the fissured ice. The descending meltwater may flow to the terminus through a tunnel, joining the other meltwater draining down the tapering front.
