Grønfjellåga
Grønfjellåga is a river in the municipality of Rana in Nordland county, Norway. The long river's source is the lakes Kallvatnet and Kopparvatnet. It then flows through the Grønfjelldalen valley while absorbing several smaller rivers, before it flows out as a tributary to the river Ranelva at the Dunderforsen waterfall.These photos are from a place east of Stupforsen:
