Yeah, you have swamps, I went to some swamp too not that far away. The swamps in Iceland are pretty different, most of them are stealth swamps, you're just walking and the landscape looks the same for miles, then all of a sudden your foot sinks half a meter into the ground out of nowhere. The vegetation above the swamp I saw in finland looked different than where the swamp was not. It was interesting, and I'm amazed someone went through the effort to build a bridge over the humongous damn thing.
After going to finland I have a new most hated insect species too, nasty little biters, I think you guys called them barma or something, no idea what they are in english, but holy fucking shit these little assholes bite! Whole fucking chunk gone off my foot out of nowhere.
