A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano.
In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces.
The word derives, via the Latin monolithus, from the Ancient Greek word μονόλιθος (monólithos), from μόνος (mónos) meaning "one" or "single" and λίθος (líthos) meaning "stone".
Large, well-known monoliths include:
A structure which has been excavated as a unit from a surrounding matrix or outcropping of rock. [10]
Oddly shaped rock pillars sculpted by wind and sea create the unique islandscape of the natural reserve
Several animal and plant species present on the islands of the Mingan Archipelago and the surrounding landscape are endangered or at risk
close to a thousand islands and islets sprinkled along 93 miles from east to west, 24,711 acres
the shoreline at low tide reveals seemingly endless tide pools full of barnacles, green sea urchins, sea stars and other small invertebrates.
