Just looked up the location of the erupting volcano on Google Earth - erupting right under a large glacier (jökull means glacier in Icelandic) and realized that my sister Sanna and I spent a day hiking, taking pictures and painting within view of it, in the Thorsmörk wilderness. I actually have a plain air rendition of it for you to see.
We also crossed the river Krosso, in a huge many wheel drive vehicle both coming and going. A huge challenge on the late afternoon return when the river was up from the glacial melt. At the end of the day we ran into a wedding party all mounted on the beautiful small Icelandic horses.
