From Wikipedia, the free encyclopedia

Grønfjellåga («the river of the green mountain») is a river in Rana municipality, county of Nordland, Norway. The river has its outlet in the lakes of kallvatnet and kopparvatnet, flows through Grønfjelldalen and absorbs several smaller rivers, before it flows out as a contributary to Ranelva at the waterfall of Dunderforsen (also called Stupforsen).
