The Northern territory of Vatnajökull National Park
North of glacier Vatnajökull, the highland plateau is divided by glacial rivers, with powerful flows in summer. The volcano Askja and the volcanic table mountain Herðubreið feature prominently in this area.
Long ago, huge glacial floods carved out the canyon of Jökulsárgljúfur in the northern reaches of this plateau. The mighty Dettifoss waterfall still thunders into the upper end of this canyon, while the scenic formations at Hljóðaklettar and the horseshoe-curved cliffs of Ásbyrgi are found farther north.
