If you explore old farm sites in remote areas in Iceland, you will find boulders, set at the boundary of a tun, a house field manured from a barn. This, in Icelandic culture, is a yard, or garden. A pretty special place. With a boulder.
These boulders are all chosen. Many have animal shapes. Many of those are ravens. Some are dwarf stones. Here on the old road up to Vatnjökull from the Fljótsdalur, it’s a raven, which is fitting, because when you walk up the trail, the ravens are watching the whole time, to see if you’re going to tumble down into the gorge and become lunch. it’s best to honour wise creatures like that.
