Geithúsaárgil ravine
Geithúsárgil is a ravine that runs down from the mouth of Sléttudalur under the roots of Grænafell in Reyðarfjörður. The river that flows down the gorge is called Geithúsaá and joins Norðurá when it comes down to the fjord. The gorge is magnificent and spectacular with criss-crossing hammer walls on each side and has been shaped by the Geithúsaá river over the centuries. The river has thus shaped the gorge and still is, but gorges are said to be the characteristics of "young waterfalls".
