It started off cold and rainy and today was the day we had scheduled to go to the famous Blue Lagoon, which is a geothermal spa that opened in 1999. It was accidentally created when a large geothermal plant was constructed to power the nearby NATO base at Keflavik Airport. The plant works by pumping water almost a mile underground, where it is heated to boiling temperatures to create steam to power the turbines. The effluent from the plant originally was intended to just flow back into the soil, but the silica concentration in the water was so high that it sealed the volcanic rocks and created this man-made reservoir. The blue-green color of the water is due to a type of algae that flourishes in the heated water (and which is very good for the skin). It is quite a sight to see.
My husband and I also had a full body massage while there. It was a fantastic day!!
