Saltstraumen (Norwegian) or Stuorstrávve (Lule Sami)[1] is a small strait with one of the strongest tidal currents in the world.

The narrow channel connects the outer Saltfjorden to the large Skjerstad Fjord between the islands of Straumøya and Knaplundsøya.

[3][4] Up to 400 million cubic metres (110 billion US gallons) of seawater[5] forces its way through a 3 km (1.9 mi) long and 150 m (490 ft) wide strait every six hours.

The behavior of the current may differ from normal due to strong winds or when more fresh water than usual is entering into the fjord from the surrounding mountains.

These hunters lived on the edge of the ice, attracted by the abundance of fish caused by the strong currents.
