Day 10 - Return from the Circle

Once heading back from the frigid zone of 66°33', we had some fun watching a White-tailed Eagle as it eyed its dinner in the form of 2 Goosanders, birds that look like Mergansers, but aren't. The Goosanders knew the eagle was in the tree above them and were very wary, diving underwater at the slightest hint that the eagle was coming. When Ivan got out of the car to photograph the eagle (or the goosanders, whichever would work), the show was over. The eagle flew away and, since Svein had stopped in the middle of the road so we could watch this show, we headed further south toward Mo i Rana. (BTW, 'i' in Norwegian means 'in.' Rana is a municipal district and, since there are several towns in Norway with the name of Mo, this one is differentiated by adding the 'i Rana' to it.)
We visited a dam along the river in Mo. Svein told us that it is used for power in the city and it's really quite interesting. The river bottom at the base of the spillway is solid rock and we could see several holes in this bottom surface, holes that were made by very large stones getting caught in the current from the spillway flow and spun around and around until they made deep depressions in the rock. At some point in this process, the whirling stone would break up from the relentless pounding of the water and all that would remain would be a very big, and almost perfectly ball-shaped hole. There were lots of these holes of varying sizes, but all looked as though a ball had been in the hole sometime in the past.
