Having done an extensive amount of walking, I took a breather to take in a view of the Thames. It flows through southern England, and its source is in Kemble. From there it flows east before ultimately flowing into the North Sea in the Thames Estuary. References to the river go all the way back to Roman times, and human settlement along the river goes even further back. It is not exactly what I would call picturesque, and throughout most of its modern history it has served as London’s sewer and garbage dump. While the water quality of the river probably still isn’t all that great, major steps have been taken to bring it back from the literal cess pool that it once was.
