"The Long Glacier (1355m) is the second largest in Iceland. It has an area of about 950 km² and most of it rises between 1200 and 1300 m above sea level. It rests on a massif of hyaloclastite mountains." http://intotheglacier.is/about/
The Grotta Lighthouse was first built in 1897. The current structure was built in 1947 and stands 24 meteres high. The lens from the original 1897 lighthouse is still in use at the peak of this classic looking lighthouse.
A slowly melting piece of the Vatnajökull glacier sits on the black sand beach at Jökulsárlón.
