There's a reason Falljökull means the "Falling Glacier." Crashing down over hundreds of years on its way from Vatnajökull National Park to the Atlantic Ocean, it is literally a giant frozen waterfall cascading decade by decade, millimeter by millimeter in front of your eyes. It also happens to be an incredibly accessible outlet glacier. A small brook, Fallsjokulskvisl falls from the glacier and close to it are two canyons, Graenafjallsgljufur and Storalekjargljufur, also well worth checking out.
Virkisjokull is an outlet of Vatnajokull glacier and thus a part of Vatnajokull National Park. At Virkisjokull glacier you can explore impressive ice formations and crevasses, take in the scenic view of the surrounding mountains and the impressive icefall, crashing down hundreds of meters.
The tremendous power of glaciers as agents of landscape change can be understood when one sees the speed at which ice is able to flow. Their ability to shape and carve modern mountain chains can be seen all over the world, and their legacy spreads far wider, into landscapes now totally devoid of permanent ice, both upland and lowland.
The BGS Virkisjökull Glacier Observatory was established in 2009, and new equipment has been installed each year to monitor the key components of this glaciated catchment, namely climate, ice dynamics, landscape change, hydrology and groundwater.
