Niitusjohka represents according to Bjørlykke (1966), the discovery point for the first grains of alluvial gold found in the whole of the Karasjok area. The discovery was made by Tellef Dahll in 1866. In 1891 he gave the first account on the gold fields in the Karasjok area.

Abstrakt:
The first find of alluvial gold in Finnmarken was made by inspector (bergmester) Tellef Dahll in 1866 in sand from a small river named Nitusjokka near Karasjok. During the following 5 years gold deposits were found in all the rivers of the Tana river systm and the Alta and Reisa rivers. Gold has been found in small amount in all kinds of sand- and gravel deposits and also in the unwashed moraine deposits. The gold fields which have been subject to production or prospection work are situated at the upper parts of the rivers. The occurrences of alluvial gold in Finnmark may be classified in The following way: 1. Preglacial accumulations undisturbed by ice erosion during the ice age. 2: Preglacial accumulations disturbed and redeposited in moraines and fluvioglacial deposits. 3. Accumulations in postglacial river beds. The gold in these deposits seems chiefly to have been washed out from the moraines. Mineralogical analyses of the mineral composition of the gold-bearing sand and gravel have been carried out. The minerals of the gold-bearing deposits may be divided in two groups: 1. Minerals belonging to the surrounding solid rock. 2. Minerals which do not seem to belong to the solid rock in the neighbourhood of the deposits.

Forkortet: Dr. Dahll commmenced his investigations in Finnmark 1866. The same year he found alluvial gold in the river Karasjok, tributary to the river Tana, which latter constitutes along a great part of its course the the frontier of Norway and Sovjet. Washing for gold was tried during the years following the discovery but it has now ceased on the Norwegian side. Across the border, in Finland, it is still carried on. Dr Dahll has also the honour of being the first investigator of the Jurassic country on Andøya.
