As unremarkable as moss may seem here, in temperate climates, it can take on fantastic forms in Iceland. It is one of the few types of flora that thrives in this cold, damp climate. While driving the ring road east of Vik, I came upon vast lava fields that at first glance appeared to be green crumb cake. In fact, each rock and boulder had grown a thick coat of moss and lichens. When I left the car to get a closer shot, I found jumping from rock to rock to be like trampolining, the stuff was so thick and spongy.
