2015 is a year with 53 weeks. The most impressive trip I've been on this year was clearly the one to Iceland. A good reason, therefore, to select another one from Iceland as the last photo of the week in 2015.
I took this photo in the Kerlingarfjøll mountain range. Due to the volcanic activity, these mountains have amazing colours and lines. The sulfur vapours, escaping through different vents, lends the scene the mysterious feel of a new born plant. The only hint at "civilisation" comes from the stairway leading up one of the hills.
