An aerial view captures a wide river mouth merging into an expansive body of water, with sandy shorelines on either side. The water exhibits varying shades of brown and green, likely due to sediment. In the distance, industrial structures and cranes are visible along the shore, contrasting with the natural landscape of the sandy beach. Wispy clouds dot the blue sky, creating a serene atmosphere.

The River Mersey is between 1 and 3 miles wide at various points, and yet only a narrow channel is safe for ships. You can just about see the green and red buoys showing where is safe to sail. Here a small boat skims across the top of a sandbank at low tide, with just enough water to get by.
