Water Flows the Wrong Way at the Edge of Rivers

At the edge of rivers, friction causes water to slow down. This leads to eddies –¬†water that turns in circles. In some places the eddies gang up and cause a narrow stream to go against the main flow of the river.

This was one of the many signs I found recently on a recent trip to north-west Scotland. For the full set, please see The Collection.
