The Krossanes Cliffs north of River Glera and east of the Horgarbraut street have clearly been shaped by glacier erosion. Hidden people live in the Stofuklopp Rock. In 1962 it was planned to quarry this outcrop. Dynamite had been placed there when the foreman heard about the settlement of hidden people. He immediately contacted the manager of the Krossanes factory and work was stopped.

A young lad who had the gift of seeing was called in to talk to the hidden people and after several discussions with him and meetings among themselves, they agreed to move to another rock farther west in the cliffs. In the marshlands between the cliffs are a number of pools. The thriving avifauna there includes black tailed godwits, whimbrels, snipes, golden plovers, arctic terns, ptarmigans, gulls and ducks.

The flora is fairly rich, especially in marshland vegetation. Between Sandgerdisbot and Jotunheimar is a beautiful stretch of beach with a short point of rock called Langitangi. On the beach south of Krossanes, scurvy grass grows in among other littoral plants.
