Dendritic patterns in river mud

At low tide, the water draining down through the glutinous soft muds on the banks and bed of the River Hull, near the mouth where it flows into the Humber, carves deep dendritic patterns in the sediments. This phenomenon mirrors the action of large scale river systems in the wider landscape, and is the key to unravelling the complex stratigraphy of sedimentary rocks that have formed in past geological periods through the transport of sediments by rivers in valleys, flood plains, and deltas down to the sea.

  1. How beautiful! I agree with the first comment, that it looks like a mountain landscape from the air. I shall take a longer look at mud next time, instead of hurrying on to find the stones! 🙂


  2. Yes, I even have some aerial shots from 30,000 feet above a mountain range in north-west America that look uncannily like these natural mud sculptures.
