Stora Sjöfallet National Park  Stora Sjöfallet () is a national park in Norrbotten County in northern Sweden, in Gällivare Municipality and Jokkmokk Municipality. The national park is and the third-largest in Sweden. It is about above the Arctic Circle by the Norwegian border and lies north and south of the lake system of the Lule River. The area was declared a national park in 1909. The national park is part of the Laponian area, which is a UNESCO World Heritage Site. Stora sjöfallet is also a part of Natura 2000, which is a network for protected areas in the European Union. When the national park was created in 1909 the main reason was the great waterfall called Stour Muorkkegårttje in the Sami languages. The great waterfalls at the heart of the park were historically among the most powerful and visually striking in Europe, but relatively soon after the area was given its protected status, the government permitted hydroelectric development of the falls, which deprived the sheer drop of most of its visible water flow except for a few times a year and damaged the shorelines of Akkajaure. Later developments in this part of the park include a power line, roads, and gravel banks. Already in the 1960s the status as national park was questioned due to these severe changes, and today the area of the falls is no longer a part of the national park. Today the lake Akkajaure, that divides the park into two, is artificial. The name of the park comes from a five-level waterfall on the Lule River. Each of the five levels is named after a man who has been important in the history of Lapland. The first is SG Hermelin (Hermelin's fall), who was a great entrepreneur in the industrial history of Norrbotten. Lars Levi Laestadius, the founder of Laestadianism, and Düben, doctor and author of the book "Om lappland och lapparne", have also given their names to levels in the fall. The two last levels were named after Carl Anton Petterson, who presented the Stora sjöfallet to the Swedish people, and Henrik Adolf Widmark, who was strongly committed to the mountains of Lapland. The mountains were formed about 400 million years ago when two continents collided. The sea between them disappeared and the sediment of the seabed was pressed into a mountain range.
