The Kalixälven runs four hundred and sixty-one kilometres from the snows of Kebnekaise, Sweden's highest mountain, down through Norrbotten to the Gulf of Bothnia — one of only four great northern rivers left entirely undammed, a protected national river flowing free from source to sea. Unusually, it is fed partway down by the Tärendö, a bifurcation that bleeds more than half the water out of the neighbouring Torne; it is one of the largest natural river-splits on Earth. The Kalix suits its wild state: rather than a few great waterfalls it runs mostly smooth and broad over hard shield rock, broken by countless small rapids, through forest and mire on a gentle northern gradient. Its salmon are entirely wild, lately averaging six or seven kilos with fish to fifteen. Wading is open-river work on firm gravel and rock, the long smooth runs asking for distance more than for footing nerve.
