What is "tysfjorden"

Tysfjorden is a fjord in the municipality of Tysfjord in Nordland county, Norway. The fjord stretches southwards from Korsnes along the Ofoten fjord all the way to Hellmobotn, about to the southeast (near the border with Sweden). The island of Hulløya is located about halfway through the fjord. Tysfjorden is the deepest fjord in Northern Norway reaching to below sea level near Hulløya. There is no bridge or tunnel crossing the fjord, and no road passing the end of it inside Norway. The fjord ends 6 km from the border to Sweden. There are regular ferry crossings over the fjord from Bognes to Skarberget and from Drag to Kjøpsvik.
