Near the castle ruins, on the West Hill, are " St Clement's Caves ", partly natural, but mainly excavated by hand by the smugglers from the soft sandstone.

Much of this matrix is formed by relatively soft fragments, such as shale and some volcanic rocks, that are chemically altered and physically compacted after deep burial of the sandstone formation.

During the first settlement, c. 13, 000 BC, the village consisted of small round huts, cut into the soft sandstone of the terrace.

The water churning at the bottom of the falls ate away at the soft sandstone, eventually breaking off the hard limestone cap in chunks as the falls receded.

In some areas, the limestone is capped with a soft sandstone.

In soft sandstone, the birds themselves excavate holes nearly a metre deep.

A chine is a steep-sided river valley where the river flows to the sea through, typically, soft eroding coastal cliffs of sandstone or clays.

Most of the sand is unconsolidated ; however, in some places near the False Bay coast the oldest sand dunes have been cemented into a soft sandstone.

The latter often consist of hard rocks such as granite or gneiss, but also soft rocks such as sandstone occur.

Concrete can be made to have high compressive strength, e. g. many concrete structures have compressive strengths in excess of 50 MPa, whereas a material such as soft sandstone may have a compressive strength as low as 5 or 10 MPa.

Built of soft sandstone, the tower is very weathered, and has been partially refaced.

Higher layers of exposed sandstone are often varying shades of orange, and are often quite soft to the touch, often being very brittle, and relatively easily eroded.

It also contains thick units composed of either brown calcareous sandstone ; soft shaly sandstone interbedded with bluish-black limestone ; and interlayered greenish-gray marls and dark gray cherts.

By the 1870s the local soft red Collyhurst sandstone was deemed to be to be unsuitable for public buildings, and tough Pennine sandstones were preferred.

In just a few centuries, the rushing waters of the glacier carved the soft middle layer of sandstone into the myriad dimples and wrinkles that decorate the cliffs and grottos today.

Listed as a building of special architectural or historic interest, it was closed by East Dunbartonshire Council in June 2004, largely due to the anticipated expense of restoring a building constructed of notoriously crumbling soft sandstone.

Hoodoos form typically form in areas where a thick layer of a relatively soft rock, such as mudstone, poorly cemented sandstone or tuff ( consolidated volcanic ash ), is covered by a thin layer of hard rock, such as well-cemented sandstone, limestone or basalt.

The sandstone, when freshly exposed, is a hard, fine-grained, feldspathic, silty sandstone, but weathers easily to a soft, clayey porous material ranging from green to brown in color.

The resulting soft greenish-gray shale with beds of purple and green sandstone near its base, became the 100 feet ( 30 m ) thick Wolsey Shale Member of the Gros Ventre Formation.

For example, in Kent and Sussex in south-east England, the sandstone rock is soft and prone to erosion, so placing protection into the rock would be both damaging and unreliable.

The meteorite struck soft sandstone and limestone rocks thus its initial depth exceeded but the site was soon covered by sedimentary rocks, sand and clay.

Diatomaceous earth is a soft, siliceous, sedimentary rock made up of the cell walls / exoskeleton | shells of single cell diatoms and which readily crumbles to a fine powder.

Without these precautions, cracks in overgrown and overly brittle hoof walls are a danger, as is bruising of the soft tissues within the foot because of inadequately thick and hard sole material.

The walls of the vagina are composed of soft elastic folds of mucous membrane which stretch or contract ( with support from pelvic muscles ) to the size of the inserted penis or other object, stimulating the penis and helping to cause the male to experience orgasm and ejaculation, thus enabling fertilization.

The lungs of amphibians typically have a few narrow septa of soft tissue around the outer walls, increasing the respiratory surface area and giving the lung a honey-comb appearance.

Diatomaceous earth is a soft, siliceous, sedimentary rock made up of the cell walls of diatoms and readily crumbles to a fine powder.

He dug the soft ground below the walls and the Romans infiltrated through the city's sewage system effectively, defeating the enemy.

There is also the simultaneous approximation of the walls of the pharynx to the posterior free border of the soft palate, which is carried out by the palatopharyngeus ( pharyngeal plexus — IX, X ) and the upper part of the superior constrictor ( pharyngeal plexus — IX, X ).

A slurry wall is a technique used to build reinforced concrete walls in areas of soft earth close to open water or with a high ground water table.

The city's white marble walls, buildings, and tower were designed to catch and reflect the moonlight, and shone with a soft silver luminescence.

Prone to sinking because it was built on soft soil and a shallow foundation, floors buckled, walls and chimneys cracked ; it became unsafe and frequently required repairs.

Hence, these anatomic characteristics permit dividing the nose into nasal subunits: ( i ) the midline ( ii ) the nose-tip, ( iii ) the dorsum, ( iv ) the soft triangles, ( v ) the alar lobules, and ( vi ) the lateral walls.

Beds are usually what would be left once a stream is no longer in existence ; the beds are usually well preserved even if they get buried, because the walls and canyons made by the stream usually have hard walls, usually soft sand and debris fill the bed.

Pink: soft tissues ; light gray: bone ; blue: tendons ; red: corium ; yellow: digital cushion ; dark gray: frog ; orange: sole ; brown: walls

Sheet pile retaining walls are usually used in soft soils and tight spaces.

The track has since been changed with soft walls to improve racing safety.

Now a thing is not declared to be soft through yielding to a heavy blow, for walls yield to the battering-ram.

Researchers have found that accumulation of white blood cells, especially macrophages, termed inflammation, in the walls of the arteries leads to the development of " soft " or vulnerable plaque, which when released aggressively promotes blood clotting.

This fill was made by digging up the soft clay present in the valley below where dredges excavated the clay and water and loaded it into pumps that delivered it up into a pond created between the inner and outer walls of the dam.

The resulting wine is then aged in relatively small barrels in a labyrinth of cellars in the soft volcanic tuff, on whose walls thick blankets of fungus regulate the humidity.

The soft palmetto logs did not crack under bombardment but rather absorbed the shot ; cannon balls reportedly even bounced off the walls of the structure.

Despite Château Gaillard's reputation as a great fortress, Liddiard highlights the absence of a well in the keep as a peculiar weakness, and the castle was built on soft chalk, which would have allowed the walls to be undermined.
