This beach, in the bay called Anse de Dinan, near the settlement of Kerloch, has been affected by the oil spill of the tanker 'Prestige'. A number of tankers have foundered off the Brittany coast in recent years, and the effects are visible, especially near the high tide line, where marine action is limited.

At low water, even the headlands are accessible from the land, and reveal their features of erosion well. Here a headland shows both cave and stack features.

Contorted vertical-dipping strata will greatly influence landforms on a coast.

Caves are being eroded by marine action, working along the lines of the steep-angled strata.

In this cave, which has its own beach of cobbles and pebbles (which do the eroding when hurled at the bedrock) an arch is already in place.
Abrasion and attrition.

To the south of the headland is a bay, backed by sand dunes.

The beach is being colonised, temporarily.

Rock crevices share the ecological niches of headlands and dunes.

Dunes here have grown to a considerable height of some 20 metres or more, and the area is large enough for a robust ecosystem to establish itself.
