Kevin Crossley-Holland reflects on the magic and the menace of the Norfolk tides.

For centuries, North Norfolk lives have been shaped by the daily rhythm of the tides, creating a sense of wonder, as well as tragedy, with many stranded or lost at sea.

The shimmering creek is at low tide at Burnham Overy Staithe, the North Norfolk coastline a mesh of salt marshes, sand dunes, wild sea lavender and shingle ridges. But the whispering of the wind and the cawing of the gulls are deceptively tranquil. In a matter of hours, the furious gushing of the incoming North Sea tide signals the utter transformation of the staithe – and, in its wake, a new menace arrives. The coastline is in a constant state of flux, always shape shifting, beguiling and menacing.

For local fishermen and sailing enthusiasts, the Tide Tables are ignored at their peril; for others the rhythm of the tides provides solace and comfort. And for a local artist, the tides bring back reminders from the past, from the ancient forests of Doggerland.
