Continuing our Iceland travelogue, the Grábrók Crater in Borgarfjörður was formed in a fissure eruption less than 3000 years ago. It is 173 meters across. The eruption spread a huge number of lava boulders in the surrounding area. (That's not the crater above. It is the path leading up to it. The wind was too strong to get past this point and climb up to the ridge overlooking the crater!)Visually, I found the most distinctive feature of the area to be the growth of lichen on the lava. It creates a surrealistic snow-like covering. Color leaves your field of view, and you mainly see gray and white.
