Mountain pass in the context of "Surami Pass"

A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets.

Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types.

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 Llogara Pass (Albanian: Qafa e Llogarasë); (also Llogora in local dialect) is a high mountain pass within the Ceraunian Mountains along the Albanian Riviera. It connects the Dukat Valley in the north with Himarë in the south. Orikum is the nearest city on the northern side of the pass and the village of Dhërmi in the south.

The Llogara Pass is also part of the Llogara National Park, which spans an area of 10.1 km (3.9 sq mi). In November 1912, during the Himara revolt a Greek unit was positioned on the Llogara in order to defend the region of Himara from Ottoman-Albanian attacks from the direction of Vlorë.

Likhi Range (Georgian: ლიხის ქედი, romanized: likhis kedi) or Surami Range (Georgian: სურამის ქედი, romanized: suramis kedi) is a mountain range in Georgia, a part of the Caucasus Mountains. It connects the Greater Caucasus and Lesser Caucasus ranges and belongs to the Dzirulula denudative Plateau. It is watershed of the Black and Caspian seas basins and divides the country climatically and geomorphologically.

The highest point in the range is the Ribisa mountain, at 2,470 m (8,100 ft) above sea level. The lowest and most important mountain pass is the Surami Pass at an elevation of 949 m (3,114 ft) which links eastern and western Georgia. A railroad (in the tunnel) runs through the pass, as well as the Zestaponi-Khashuri highway. A southern portion of the Likhi range was historically known as Ghado.

Guanzhong (Chinese: 关中, formerly romanised as Kwanchung) region, also known as the Guanzhong Basin, Wei River Basin, or uncommonly as the Shaanzhong region, is a historical region of China corresponding to the crescentic graben basin within present-day central Shaanxi, bounded between the Qinling Mountains in the south (known as Guanzhong's "South Mountains"), and the Huanglong Mountain, Meridian Ridge and Long Mountain ranges in the north (collectively known as its "North Mountains"). The central flatland area of the basin, known as the Guanzhong Plain (关中平原; pinyin: Guānzhōng Píngyuán), is made up of alluvial plains along the lower Wei River and its numerous tributaries and thus also called the Wei River Plain. The region is part of the Jin-Shaan Basin Belt, a prominent section of the Shanxi Rift System, and is separated from its geological sibling — the Yuncheng Basin to its northeast — by the Yellow River section southwest of the Lüliang Mountains and north of the river's bend at the tri-provincial junction among Shaanxi, Shanxi and Henan.

The name Guanzhong means "within the passes", referring to the four major mountain pass fortresses historically defending the region. The region was the traditional heartland of Qin state during Zhou dynasty and thus often nicknamed the "800 li of Qin land". The Yellow River, Lüliang Mountains and the eastern end of the Qinling separate the region from the (then) politically orthodox Central Plain, which is located east of the strategic Hangu Pass and therefore was historically referred as the Guandong ("east of the pass") region by the Qin people, who later conquered the eastern states and unified China as a centralized empire — the Qin dynasty — for the first time during the 3rd century BC. Afterwards, subsequent prominent dynasties such as the Han and Tang (both considered China's historical golden ages) also had the crownland established in the Guanzhong region.

The Shanhai Pass (simplified Chinese: 山海关; traditional Chinese: 山海關; pinyin: Shānhǎi Guān; lit. 'Mountain Sea Pass') is a major fortified gateway at the eastern end of the Great Wall of China and one of its most crucial fortifications, as the pass commands the narrowest choke point in the strategic Liaoxi Corridor, an elongated coastal plain between the Yan Mountains foothills and the Bohai Sea, which is the only easily traversable landway between North and Northeast China. It is located in present-day Shanhaiguan District, Qinhuangdao, Hebei province, on the east bank of the Shi River, with defensive walls stretching from the Yan Mountains all the way to the shores of the Liaodong Bay.

Throughout Chinese history, garrisons around the pass served as frontline defensive outposts against raids and incursions into the North China Plain by various non-Sinitic ethnic groups from the Northeast (also known as Manchuria since the 19th century), including the Dongyi, Donghu (Xianbei and Wuhuan), Khitan and Jurchen (Manchus). The current Shanhai Pass was built during the early Ming dynasty as the easternmost fortification of the Ming Great Wall, and was extensively reinforced after Yongle Emperor moved the capital from Nanjing to Beijing following the Jingnan campaign, making it the most important defensive barrier in all of China, as it shielded the heartland region around the imperial capital. The pass' strategic location dictated that without mounting a costly direct siege, the only way an invading army can get past the pass' defense was to circumvent it around the north through a few treacherously narrow mountain passes deep within the Yan Mountains, which would make it very difficult to maintain supply lines and thus any sizeable invasions. This defensive significance therefore earned the pass the famous nickname "Greatest Pass Under Heaven" (天下第一关).

The Karakoram Pass (Uyghur: قاراقۇرۇم ئېغىزى) is a 5,540 m or 18,176 ft mountain pass between India and China in the Karakoram Range. It is the highest pass on the ancient caravan route between Leh in Ladakh and Yarkand in the Tarim Basin. The name 'Karakoram' comes from a Turkic language meaning 'Black Gravel'.

Historically, the high altitude of the pass and the lack of fodder were responsible for the deaths of countless pack animals while the route was notorious for the trail of bones strewn along the way. There is an almost total absence of vegetation on the approaches to the pass.

The Col du Galibier (el. 2,642 metres (8,668 ft)) is a mountain pass in the southern region of the French Dauphiné Alps near Grenoble. It is the eighth highest paved road in the Alps, and recurrently the highest point of the Tour de France.

It connects Saint-Michel-de-Maurienne and Briançon via the col du Télégraphe and the Col du Lautaret. The pass is closed during the winter. It is located between the massif d'Arvan-Villards and the massif des Cerces, taking its name from the secondary chain of mountains known as the Galibier.

A col in geomorphology is the lowest point on a mountain ridge between two peaks. It may also be called a gap or pass. Particularly rugged and forbidding cols in the terrain are usually referred to as notches. They are generally unsuitable as mountain passes, but are occasionally crossed by mule tracks or climbers' routes. Derived from the French col ("collar, neck") from Latin collum, "neck", the term tends to be associated more with mountain than hill ranges. The distinction with other names for breaks in mountain ridges such as saddle, wind gap or notch is not sharply defined and may vary from place to place. Many double summits are separated by prominent cols.

The height of a summit above its highest col (called the key col) is effectively a measure of a mountain's topographic prominence.
