Pointe de la Jonction

One of the largest lakes in Western Europe, Lake Geneva is a crystal clear paradise. The turquoise waters of the Rhône River feed the lake after flowing down from the Alps. And when the Rhône flows out of the lake, it's nearly just as clear due to its slow movement.

However, the nearby Arve River moves much faster, stirring up sand and mud, which makes it take on a milky white hue.

When the two rivers meet, a fascinating effect takes place, as the difference in speed, temperature, and water density prevents the rivers from mixing at the junction.

Depending on the time of year and the amount of water in either river, the effect can become more or less pronounced, sometimes resulting in a beautiful turbulent pattern at their meeting point.
