Rocks

We had our camera clubs photowalk this month at Imatra, where we walk along the riverbed of Vuoksi. At now the race was not flowing thus we were able to see all fantastic details on the bottom of the race. It might be a bit hard to figure out the actual size of those rocks, but maybe this image helps a bit. That race has been born 5000 years ago and has been confined nowdays as you can see from the link.

Here is an youtube live video of the race in action.
