Herðubreið (Icelandic pronunciation: [ˈhɛrðʏˌpreiːθ] , broad-shouldered) is a tuya in the northern part of Vatnajökull National Park, Iceland. It is situated in the Highlands of Iceland at the east side of the Ódáðahraun ([ˈouːˌtauːðaˌr̥œyːn]) desert and close to Askja volcano. The desert is a large lava field originating from eruptions of Trölladyngja and other shield volcanoes in the area. Herðubreið was formed beneath the ice sheet that covered Iceland during the last glacial period.
