Lapland, Sweden in the context of "Norrbotten County"

Jämtland (Swedish: [ˈjɛ̌mːtland] ) is a historical province (landskap) in the centre of Sweden in northern Europe. It borders Härjedalen and Medelpad to the south, Ångermanland to the east, Lapland to the north and Trøndelag and Norway to the west. Jämtland covers an area of 34,009 square kilometres, 8.3% of Sweden's total area and is the second largest province in Sweden. It has a population of 115,331, the majority of whom live in Storsjöbygden, the area surrounding lake Storsjön. Östersund is Jämtland's only city and is the 24th most populous city in Sweden. The historical province is one of the least densely populated.

Jämtland was originally an autonomous republic, its own nation with its own law, currency and parliament. Jämtland was conquered by Norway in 1178 and stayed Norwegian for over 450 years until it was ceded to Sweden in 1645. The province has since been Swedish for roughly 370 years, though the population did not gain Swedish citizenship until 1699. The province's identity is manifested with the humorous culture and marketing concept of a republic within the kingdom of Sweden, although this is only done semi-seriously.

Jämtland County (Swedish: Jämtlands län, Southern Sami: Jiemthen leene) is a county or län in Sweden. It consists of the provinces of Jämtland and Härjedalen, along with minor parts of Hälsingland and Ångermanland, plus two small strips of Lapland and Dalarna. It borders the counties of Dalarna, Gävleborg, Västernorrland, and Västerbotten, as well as the Norwegian county of Trøndelag. It measures 49,443 km (19,090 sq mi) and constitutes 12% of Sweden's total area, making it the country's third largest county. The capital is Östersund. The county governor and leader of the administrative board, as appointed by the Swedish government, has been Marita Ljung since 2021.

The county was established in 1810, at the time it consisted only of the provinces of Jämtland and Härjedalen, which is why the coat of arms is a shield parted per fess with their provincial arms. King Carl XVI Gustaf is occasionally referred to as Duke of Jämtland after his title of king.

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.
