Ledging

Ledging is a term used to describe the creation or use of ledges, or horizontal platforms, on rock faces, cliffs, or built surfaces. It can refer to natural processes that produce ledges through erosion or sedimentary layering, creating shelf-like steps that influence drainage, vegetation, and microhabitats. It can also denote artificial construction or modification to form ledges for access, stabilization, or habitat enhancement, such as quarry benches, masonry shelves, or retrofit of rock faces in stabilization projects.

In geomorphology, ledges are natural features that form as resistant strata weather or erode more slowly than surrounding rock. These features can affect slope stability, drainage patterns, and ecosystem niches. In construction and engineering, ledging describes shaping or installing shelves to improve access, support, or stability on cut faces, embankments, or architectural elements. In mountaineering or shelter-building contexts, the term is sometimes used informally to describe placing temporary ledges to rest or shelter on a route, though usage is not standardized and varies by region.

Safety and regulation are important considerations in ledging activities. Work at height and on rock faces carries risks of falls and rockfall, making risk assessment, proper training, and adherence to safety protocols and regulatory requirements essential.

The term derives from the noun ledge with the -ing suffix to indicate the action. Ledging is relatively uncommon and is often regional or field-specific; related terms include bench, shelf, terrace, and rock shelter. See also: ledge, bench (geology), terrace, rock shelter.
