We took a short hike to the edge of Svínafellsjökull Glacier, which you can get right up next to. When we were there the fog was flowing down it like water, and up over the neighboring hill.
In this picture you can also see how the sandy slope appears to be layered on that hill. This is caused not (as I suspected) by repeated ash from volcanoes, but because the land thaws out and slides annually, forming a pattern like tree rings that’s common on a lot of the similar hills we saw throughout our trip.
