The day started with a visit to Godafoss, the waterfall of the the gods, named after the Viking pagan gods. From there we headed to Lake Myvatn, an area with an enormous amount of geothermal energy. The area at Hverir was a field of bubbling mud pots, small geysers, and steam vents. Nearby the geothermal power plant at Kraffla was the first such plant in Iceland. Then it was on to Husavik for an evening whale watching cruise where we saw several humpback whales while cruising in the cold Arctic Ocean.
