Uluru, Northern Territory, Australia, is often referred to as the biggest monolith, but that is generally avoided by geologists. While the surrounding rocks were eroded, the rock survived as sandstone strata making up the surviving Uluru 'monolith'.
A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains, or a single large piece of rock placed as, or within, a monument or building. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock.
