The sandy wasteland between the glacier and the sea caused by jökulhlaups is called Skeiðarársandur, and is a typical Sandur.
Pokrajina je zelo podobna nekaterim v Alpah, vendar je nastala v tisočih letih pod različnimi vplivi vulkanskih izbruhov Öræfajökull in erozije vode (ledenika Skeiðarájökull in Skaftafellsjökull), rek Skeiðará, Morsá in Skaftafellsá.
