Iceland report - day 4

Not a paddling report, though I wish it was! We have been blessed with magnificent weather for all but one day and most of that was at night.
So far we have seen a geothermal power station ( neat for a geoscience teacher!), a spectacular waterfall (Gulfoss), a spectacular geyser, all kinds of steam vents emanating from the ground, the rift where Europe and north America are splitting apart, and for the past day we have been on Heimaey island, the site of a dramatic eruption in 1973 which almost "swallowed" the town. The volcanic landscape here is magnificent, and we have also had great birding (our favourites are the puffins which are easy to see in many places). We head back to the mainland tomorrow and plan to head counter clockwise around Iceland.
