Today we walked Svinyfallsonhiskull Swinfallsjokeall Svensellsseahshells a big honking glacier which is part of Vatnajökull National Park in Skaftafell, in the south east part of Iceland. The glacier is atop the Öræfajökull volcano which has errupted twice in recorded history, most recently in 1728. So there's lots of volcanic ash and rock amidst the ice. I didn't see any yaks, but otherwise it was pretty amazing. Here are some photos.
