The sun has set on the Beauly Firth, as viewed from the Kessock Bridge.

The tide is turning, and the horizontal line across the frame is starting to move towards me. It's where the freshwater from the mouth of the River Ness (on the left) is now pushing back against the falling saltwater from the open sea. The fresh and salt waters don't immediately mix with one another, and a line is often apparent between them. Not only are their salinity levels very different, but their temperatures are too. The fresh water often being much colder. I always find it of interest to see how the waves do, or don't transfer, across the junction line.

The man-made structure in the water is a (red) channel marker for shipping. Incoming vessels must keep it to their port side (left to land-lubbers), to avoid running aground. Prior to the Inverness Marina being built, some of the yacht sailing fraternity wouldn't bother about this, or were ignorant of it. Almost every year there'd be one that would learn their mistake. They would end up stuck in the mud for almost a fortnight, until the next big enough tide finally lifted the boat clear.

The smoothness of the foreground saltwater is split by a pair of Otters swimming across the scene.
