Arête in the context of "Frost weathering"

A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional, erosional, tectonic, or a combination of these in origin and can consist of either bedrock, loose sediment, lava, or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements.

A ribbon lake is a long and very deep, finger-shaped lake, usually found in a glacial trough. As such, a ribbon lake is one of a number of glacial landscapes, including arêtes, corries, rock lips, rock basins and terminal moraines.

Such a lake's formation begins when a glacier moves over an area containing alternate bands of hard and soft bedrock. The sharp-edged boulders that are picked up by the glacier and carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. On either side of the rock basin, the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars, which act as dams between which rainwater may accumulate after the retreat of the ice age, filling up the rock basin and creating a ribbon lake. A ribbon lake may also form behind a terminal or recessional moraine, both of which also act as dams, enabling water to accumulate behind them.

Snowdon (/ˈsnoʊdən/), or Yr Wyddfa (Welsh: [ər ˈʊɨ̞̯ðva] ), is a mountain in Snowdonia in North Wales. It has an elevation of 1,085 metres (3,560 ft) above sea level, which makes it both the highest mountain in Wales and the highest in the British Isles south of the Scottish Highlands. Snowdon is designated a national nature reserve for its rare flora and fauna, and is located within Snowdonia National Park.

The rocks that form Snowdon were produced by volcanoes in the Ordovician period, and the massif has been extensively sculpted by glaciation, forming the pyramidal peak of Snowdon and the arêtes of Crib Goch and Y Lliwedd. It is part of the larger Snowdon range, which includes Garnedd Ugain, Yr Aran, and Moel Eilio. There are several lakes on the mountain, the largest of which is Llyn Lydaw (110 acres (45 ha)), located on the eastern flank at 1,430 ft (440 m).

Koncheto (Bulgarian: Кончето [ˈkɔnt͡ʃɛto], lit. 'foal') is a name given to a knife-edge ridge in the Pirin Mountains in Bulgaria, at an elevation of approximately 2,810 metres, between the peaks Banski Suhodol (2,884 meters) and Kutelo (2,908 metres). There are steep slopes on either side: the northwestern side is almost vertical and 300–400 metres deep, while the southwestern side is less steep (approximately 30 degrees) but deeper (800 metres). There is a steel cable stretched along the top of the ridge to help hikers across. It is said that some less experienced hikers go through Koncheto by saddling the ridge edge like a horse and slowly advancing, hence its name.

Carrauntoohil, Carrauntoohill or Carrantuohill (/ˌkærənˈtuːəl/ KARR-ən-TOO-əl; Irish: Corrán Tuathail [ˌkɔɾˠaːn̪ˠ ˈt̪ˠuəhəlʲ], meaning "Tuathal's sickle") is the highest mountain in Ireland at 1,038.6 metres (3,407 feet 6 inches). It is on the Iveragh Peninsula in County Kerry, close to the centre of Ireland's highest mountain range, MacGillycuddy's Reeks. Carrauntoohil is composed mainly of sandstone, whose glaciation produced distinctive features on the mountain such as the Eagle's Nest corrie and some deep gullies and sharp arêtes in its east and northeastern faces that are popular with rock and winter climbers.

As Ireland's highest mountain, Carrauntoohil is popular with mountain walkers, who most commonly ascend via the Devil's Ladder route; however, Carrauntoohil is also climbed as part of longer mountain walking routes in the MacGillycuddy's Reeks range, including the 15-kilometre (9+1⁄2 mi) Coomloughra Horseshoe or the 26-kilometre (16 mi) MacGillycuddy's Reeks Ridge Walk of the entire mountain range. Carrauntoohil, and most of the range is held in private ownership and is not part of any Irish national park; however, reasonable access is granted to the public for recreational use.

Maesglase is a mountain in Snowdonia, North Wales, situated approximately four miles to the south-west of Aran Fawddwy. It is the highest of the Dyfi Hills.

It can be reached by an easy but steep walk through the forestry from Dinas Mawddwy or directly from the bwlch on the A470. Ascending Maesglase provides an opportunity to climb several other nearby peaks including Maen-Du, Craig Rhiw-erch, Waun-oer, Mynydd Dolgoed and Cribin Fawr which are linked by a series of ridges and arêtes.

The Ruby Mountains (Shoshoni: 'Duka Doya', meaning “Snowcapped”) are a mountain range, primarily located within Elko County with a small extension into White Pine County, in Nevada, United States. Most of the range is included within the Humboldt-Toiyabe National Forest. The range reaches a maximum elevation of 11,387 feet (3,471 m) on the summit of Ruby Dome. To the north is Secret Pass and the East Humboldt Range, and from there the Rubies run south-southwest for about 80 miles (130 km). To the east lies Ruby Valley, and to the west lie Huntington and Lamoille Valleys. The Ruby Mountains are the only range of an introduced bird, the Himalayan snowcock, in North America. The mountain range was named after the garnets found by early explorers. The central core of the range shows extensive evidence of glaciation during recent ice ages, including U-shaped canyons, moraines, hanging valleys, and steeply carved granite mountains, cliffs, and cirques.

Crib Goch is a knife-edged arête in the Snowdonia National Park in Gwynedd, Wales. The name means "red ridge" in Welsh.

The highest point on the arête is 923 metres (3,028 ft) above sea level. All routes which tackle Crib Goch are considered mountaineering routes in winter or scrambles in summer—meaning that they must cross "graded territory" as defined in Steve Ashton's Scrambles in Snowdonia. The easiest of these lines (the ‘bad step’ part of the route) is given a scrambling grade of Grade 1 (the most difficult being Grade 3—routes more difficult than Grade 3 are considered rock climbs).
