There has been an on going aeolian transport of sand into the valley for the last centuries, and it has formed a large sand field in the middle of the valley and a sandspit at the beachfront.
Þar hefur átt sér stað stórfellt sandfok inn í dalinn síðustu aldir, sandfok sem hefur myndað stórt sandflæmi í dalnum og sandodda meðfram ströndinni.
