A boulder wall, also spelled boulder-walls or bowlder-wall, is a kind of wall built of round flints and pebbles, laid in a strong mortar. It is used where the sea has a beach cast up, or where there are plenty of flints.

Bouldering is a form of free climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses. While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls. Unlike free solo climbing, which is also performed without ropes, bouldering problems are usually less than six metres (20 ft) tall. Traverses, which are a form of boulder problem, require the climber to climb horizontally from one end to another. Artificial climbing walls allow boulderers to climb indoors in areas without natural boulders. In addition, bouldering competitions take place in both indoor and outdoor settings.
Flint is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires.
Flint is the largest city and seat of Genesee County, Michigan, United States. Located along the Flint River, 66 miles (106 km) northwest of Detroit, it is a principal city within the region known as Mid Michigan.

Amersfoort is also one of the largest Dutch railway junctions with its three stations—Amersfoort Centraal, Schothorst and Vathorst—due to its location on two of the Netherlands' main east to west and north to south railway lines. The city was used during the 1928 Summer Olympics as a venue for the modern pentathlon events. Amersfoort marked its 750th anniversary as a city in 2009.
Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration. The original Germanic term knopp meant to strike, shape, or work, so it could theoretically have referred equally well to making statues or dice. Modern usage is more specific, referring almost exclusively to the hand-tool pressure-flaking process pictured. It is distinguished from the more general verb "chip" and is different from "carve", and "cleave".
Master James of Saint George, ,, , was a master of works/architect from Savoy, described by historian Marc Morris as "one of the greatest architects of the European Middle Ages".

Diamicton is a terrigenous sediment that is unsorted to poorly sorted and contains particles ranging in size from clay to boulders, suspended in an unconsolidated matrix of mud or sand. Today, the word has strong connotations to glaciation but can be used in a variety of geological settings.
Cyclopean masonry is a type of stonework found in Mycenaean architecture, built with massive limestone boulders, roughly fitted together with minimal clearance between adjacent stones and with clay mortar or no use of mortar. The boulders typically seem unworked, but some may have been worked roughly with a hammer and the gaps between boulders filled in with smaller chunks of limestone.
Hertfordshire puddingstone is a conglomerate sedimentary rock composed of rounded flint pebbles cemented together by a younger matrix of silica quartz. The distinctive rock is largely confined to the English counties of Buckinghamshire and Hertfordshire but small amounts occur throughout the London Basin. It is quite commonly found in fields in and around Chesham, where pieces can be seen as boundary stones and in rockeries. Despite a superficial similarity to concrete, it is an entirely natural silcrete. A fracture runs across both the pebbles and the sandy matrix as both have equal strength unlike concrete where the pebbles remain whole and a fracture occurs only in the matrix. Like other puddingstones, it derives its name from the manner in which the embedded flints resemble the plums in a pudding. It forms the local base of the Upnor Formation of the Lambeth Group.
Silex is any of various forms of ground stone. In modern contexts the word refers to a finely ground, nearly pure form of silica or silicate.

Denghoog is a Neolithic passage grave dating from around 3000 BC on the northern edge of Wenningstedt-Braderup on the German island of Sylt. The name Denghoog derives from the Söl'ring Deng (Thing) and Hoog (Hill).
In architecture, flushwork is the decorative combination on the same flat plane of flint and ashlar stone. If the stone projects from a flat flint wall then the term is proudwork, as the stone stands "proud" rather than being "flush" with the wall.
In the sport of bouldering, problems are assigned technical grades according to several established systems, which are often distinct from those used in roped climbing. Bouldering grade systems vary widely in use and include the Hueco "V" grades, Fontainebleau technical grades, route colors, Peak District grades, and British technical grades. Historically, the three-level "B" system and even the Yosemite Decimal System were also used.
