Abisko National Park in the context of "Abisko"

A cirque (French: [siʁk]; from the Latin word circus) is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic: coire, meaning a pot or cauldron) and cwm (Welsh for 'valley'; pronounced [kʊm]). A cirque may also be a similarly shaped landform arising from fluvial erosion.

The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the downstream limit of the glacial overdeepening. The dam itself can be composed of moraine, glacial till, or a lip of the underlying bedrock.

Lapporten (Swedish: "The Lapponian Gate") or Tjuonavagge (Northern Sami: Čuonjávággi, "Goose Valley") is a U-shaped valley located just outside Abisko National Park in Lapland in northern Sweden, one of the most familiar natural sights of the mountains there. The valley is bounded to the southwest of the mountain Nissuntjårro (1,738 m) and in the northeast of Tjuonatjåkka (1,554 m). In the middle of the valley lies Lake Čuonjájávri, 950 metres above sea level. The terrain is easy to walk but has no marked trail. Lapporten is in the Nissuntjårro Natura 2000 site. A world record in highline was set by 4 Germans crossing the 2.1-kilometre (1.3 mi) distance between the mountains on a slackline more than 500 metres (1,600 ft) above ground.

Abiskojokk or Abiskojåkka (Northern Sami: Ábeskoeatnu) is a river in the Abisko National Park in northern Sweden. The upper part of the river is called Kamajokk or Kamajåkka.

Torneträsk or Torne träsk (Swedish: [toːɳɛˈtrɛsːk]; Saami: Duortnosjávri; Finnish and Meänkieli: Tornio or Torniojärvi) is a lake in Kiruna Municipality, Lapland, Norrbotten County in Sweden, in the Scandinavian Mountains. Träsk is the local word for lake (in Standard Swedish it means "swamp"). It is the sixth-largest lake in Sweden, with a total area of 330 square kilometres (130 square miles) and a length of 70 kilometres (43 miles). The lake drains to the south-east through Torne river. South-west of the lake lies the Abisko National Park and the UNESCO World Heritage Site Laponian area.

Torneträsk originated from the remnant of a glacier, which has given the lake its depth of 168 metres (551 feet), making it the second-deepest lake in Sweden. It is usually ice-covered from December through June, with variations dependent on temperature variations.
