Morsárfoss is the tallest waterfall in Iceland, located in Morsárjökull Glacier. It was only recently discovered and has ousted Glymur Waterfall from its top spot on the list of Iceland’s tallest waterfalls. Morsárfoss Waterfall came into being only a few years ago, the result of a receding glacier.
Morsárfoss is located in the southeast of Iceland in Skaftafell national park.
I haven’t seen any good picture from which I can say Morsárfoss is a real waterfall. It looks to me a rather tiny stream of melted water.
