Today is geology day. I have to admit, this was kind of new to me, but still… Around my hometown there are a lot of famous mountain, and the most famous is Torghatten that have a gigantic hole thru the entire mountain, and is quite the phenomenon in the geology field. You get a sense of the size of this hole in the image below. So today there where an excursion up to the mountain, and a professor gave a lecture about the mountain and how it have been shaped and so on. Very nice hike, and quite interesting lecture.
