Mardalsfossen

Mardalsfossen is a waterfall in Molde Municipality in Møre og Romsdal county, Norway. It is sometimes referred to as one of the tallest waterfalls in Europe. The falls are on the Mardøla river which flows out of a hanging valley into the lake Eikesdalsvatnet, about 2 km northwest of the village of Eikesdalen. The waterfall was depicted in the coat of arms of the old Nesset Municipality.

The total fall is 705 m according to SSB, 645 m according to World Waterfall Database (WWD). WWD reports that the SSB typically includes the head measurement for waterfalls that are situated within a hydroelectric system, resulting in a greater height estimate. Mardalsfossen is a tiered waterfall consisting of two large drops and several smaller ones lower down. It is on average 12 m wide, but it can reach up to 30 m wide. The highest vertical drop is one of the tallest in Norway. As with figures for the total height, discrepancies have been reported in the estimated height of each vertical drop. According to the SSB, the upper vertical drop is 358 m, while the WWD surveyed it as 320 m.

The water, which has been tapped for hydroelectric use, flows over the falls during the summer tourist season of 20 June to 20 August. At other times the water is channeled through the hydroelectric scheme. The highest rate of flow ever recorded in the falls is 45 m3/s. Summer flow is currently limited to less than 3 m3/s.

In 1970 Arne Næss, the Norwegian founder of the Deep Ecology movement, tied himself with 300 others in protest against the building of a dam and the subsequent removal of the waterfall.

Between June 2014 and August 2015 Antony Gormley’s Another Time was on view in the mist from the waterfall and formed the official start of the Mardalsfossen Art Project.

Name
The first element is from the name of the valley Mardalen and the last element is the finite form of foss which means "waterfall". The name of the valley is a compound of an old river name Mara (now Mardøla) and the finite form of dal which means "dale" or "valley". The old name of the river is probably derived from the verb mara which means "rub", "grave", "dig" or "die."
