Two views of gorge cut by the Leirvogsá river, into móberg and Pleistocene lavas. The deep gorge is the reult of rapid downcutting by the river as the land surface rose isostatically following deglaciation around 10,000 years ago. On the left is a view looking up the river which shows the móberg mountain of Mosfell, while on the right is a view looking down the river.
