SH7878 : Sand dunes and ripples
taken 4 years ago, near to Tywyn, Conwy, Wales
Sand dunes and ripples
The height of the dunes in this area of the dried-out river channel can be estimated from the height of my assistant. Deep pools of water lie in the slacks, which drain at right angles to the river channel. This conflict creates a secondary series of ripples on the dune surfaces. In the background is a fine view of the Deganwy Quay hotel atop the historical dock structure.
