Cave in the context of "Limestone"

The Lupercal (from Latin lupa "female wolf") was a cave at the southwest foot of the Palatine Hill in Rome, located somewhere between the temple of Magna Mater and the Sant'Anastasia al Palatino. In the legend of the founding of Rome, Romulus and Remus were found there by the she-wolf who suckled them until they were rescued by the shepherd Faustulus. Luperci, the priests of Faunus, celebrated certain ceremonies of the Lupercalia at the cave, from the earliest days of the City until at least 494 AD.

Karst (/kɑːrst/) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions.

Subterranean drainage may limit surface water, with few if any rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground.

Ledenika (Bulgarian: Леденика, English: icy or glacial) is a cave in the Northwestern parts of the Balkan Mountains, 16 km away from the Bulgarian city of Vratsa. Its entrance is approximately 830 m above sea level. The cave features an abundance of galleries and impressive karst formations including stalactites and stalagmites. It was first discovered around the beginning of the 20th century and has been open to tourists since 1961. Ledenika Peak on Graham Land in Antarctica is named after the cave, in recognition of its cultural importance.

The Albanian Riviera (Albanian: Riviera shqiptare, pronounced [ɾiviˈɛɾa ʃcipˈtaɾɛ]), also popularly known as Bregu, is a coastline along the north-eastern Ionian Sea in the Mediterranean Sea, encompassing the districts of Sarandë and Vlorë in south-western Albania. It forms an important section of the Albanian Ionian Sea Coast, dotted with the villages of Palasë, Kondraq, Dhërmi, Ilias,Vuno, Himara, Pilur, Kudhës, Qeparo, Borsh, Piqeras, Sasaj, Lukovë, Shën Vasil and Nivicë-Bubari.

The riviera should not be confused with the entire coastline of the country, which includes the Ionian Sea Coast, and the mostly flat Adriatic Sea Coast in the north. The Ceraunian Mountains separate the coast from the hinterland. The area is a major nightlife, ecotourist, and elite retreat destination in Albania. It features traditional Mediterranean villages, ancient castles, churches, monasteries, secluded turquoise beaches, bays, mountain passes, seaside canyons, coves, rivers, underwater fauna, caves, and orange, lemon, and olive groves. During the classical times, 48 BC during his pursuit of Pompey, Julius Caesar set foot and rested his legion at Palasë. He continued onto Llogara Pass in a place later named Caesar's Pass.

The Karaburun Peninsula (Albanian: Gadishulli i Karaburunit), also known as Cape Linguetta, is a peninsula of the Mediterranean Sea located in Southern and Southeastern Europe, which is almost completely surrounded by both the Adriatic Sea to the north and the Ionian Sea to the south. It is located in Southwestern Albania along the Albanian Ionian Sea Coast, whereas the Strait of Otranto separates it from Italy. The Strait of Mezokanal separates the peninsula from Sazan Island, while in the southeast stretches the Bay of Vlorë. In classical antiquity, its name was the "Akrokeraunian Peninsula" (Ακροκεραύνιο ακρωτήριο), whose name was derived from the eponymous Akrokeraunian mountains; this is because, in terms of geology, the Rrëza e Kanalit on the peninsula represent the continuation of said mountains, which are the highest and most extensive mountain range system that extends parallel to the Ionian Sea. Karaburun peninsula is sometimes called Ceraunian Peninsula due to the name of the mountain range. Formed during the mesozoic era of the cretaceous and paleogene period, the crests of the mountain range form a northwest-southeast line with a series of distinct peaks along its irregular structure that are broken apart by steep and unequally slopes. The highest peaks are namely, the Maja Çaderës, Maja e Flamurit, Maja e Koretës and Maja e Ilqes.

The western section comprises a rough relief and is dotted with sandy and rocky beaches, sea caves, steep cliffs and several bays amongst them Cave of Haxhi Ali, Cape of Gjuhëz, Bay of Skaloma, Bay of Arushë, Bay of Dafinë, and most notably Bay of Grama, where ships and vessels anchored during classical antiquity. On the high and steep rock faces of the bay, which served also as a marble quarry, there are hundreds of rock inscriptions dating back to the 4th century BC.

In archaeology, cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric origin. Several groups of scientists suggest that the oldest of such paintings were created not by Homo sapiens, but by Denisovans and Neanderthals.

Discussion around prehistoric art is important in understanding the history of Homo sapiens and how human beings have come to have unique abstract thoughts. Some point to these prehistoric paintings as possible examples of creativity, spirituality, and sentimental thinking in prehistoric humans.

A valley is an elongated low area often running between hills or mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas.

At lower latitudes and altitudes, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally.
