A Perfect Dome of Ice

Hofsjökull's nearly symmetrical dome rises from the desolate Central Highlands, forming a striking white landmark visible from distant mountain roads. The glacier covers an active volcanic system that last erupted around 1,800 years ago.

As the source of Iceland's longest river, the Þjórsá, this remote ice cap plays a vital role in the country's freshwater supply and hydroelectric power generation.
