Gullfoss sounds like dental floss for birds but its a very nice waterfall on the Hvita River. There's lots of exposed volcanic rock (OK that's most everywhere in Iceland) and I even noticed some ripple marks on one of the layers. I'm not the most observant field geologist out there so these were pretty obvious. None of the civilians seemed to notice them nor did they care very much about them once I pointed them out. What's wrong with me?
