This is the tallest waterfall in Iceland, Hengifoss. The land has an amazing red striation behind the water. There are a number of waterfalls passed during the long hike up to the main set of falls (the one shown here).
This is immediately recognizable for most people that have been to Iceland; the rock formation here is memorable. This was taken on the black sand beach at Vik. The rock formations can be seen from the other side of the headland as well, where there is a cave made of basalt columns like those found at the Giant's Causeway in Northern Ireland.
This is Skogafoss in Iceland ("foss" means waterfall in Icelandic, so "waterfall" shouldn't be added to the name). My friend was nice enough to stand in front of the falls for quite a while, getting soaked in the process, while I was trying to get a shot. As is usually the case in Iceland, the sky was grey and uninteresting so I focused a little tighter on the scene.
