The Prefecture of Luleå [1], 21/06/1732, ¶473:
Down by the shore to the right at GӒDDVIK ferry there rises a lively spring that they call Cold Spring. It flows vigorously and is full of ochre. The latter lies around here in considerable quantities, producing a silvery scum. It tastes rather like a sulphur spring but is quite mild. It bubbles up no more than 12 yards from the river, yet it does not freeze in the winter until it has reached the river. The hill there is not high, being no more than a fair-sized mound about 4 feet in perpendicular height above the level of the river. The opening faces north-east, or a little east of it, and people wash in it.
