Until then, the River Frome had run east through what is now the Solent, joining the Stour, the Test, the Itchen and the Hamble before reaching the sea east of where the Isle of Wight now sits. A chalk ridge held the line. Then the climate changed, sea levels rose, the south of England sank slightly into the Channel, and the chalk gave way. The Isle of Wight was cut off from the Isle of Purbeck. The Solent flooded. And the Frome, robbed of its eastern course, settled instead into a shallow basin behind the new coast, drowning the valley to make what is now Poole Harbour, a ria of about 36 square kilometres that some still call the second largest natural harbour in the world.
