The river Arve (right) flowing into the Rhône in Geneva, Switzerland

That’s the river Arve on the right, flowing into the Rhône. This point where the two rivers meet is just west of the city centre in Geneva, Switzerland. The Arve’s much lighter colour is due to the silt it picks up as it flows out of the Alps. From here, the Rhône will continue on – in a mostly southerly direction – through south-east France towards its mouth on the Mediterranean Sea.
