The Doom Bar lies at the mouth of the river Camel. For centuries it was regarded so dangerous that in a storm, sailing ships would risk being wrecked on the coast rather than negotiate the narrow channel to Padstow harbour. Deaths have occurred on the bar as recently as 1997.
At low tide I can walk across the sands from Rock to Trebetherick. The wall panel shows the outgoing tide exposing stretches of sand that starts to dry in the sun before the tide returns to wash the ripple marks away until the next low tide.
