Henley-on-Thames nautical chart print

The Thames valley as a branching sea inlet

Raise the sea to 120 metres above today’s and the Thames valley becomes a long, branching inlet, with the Chiltern valleys running off it as creeks. The deepest water, where the river runs now, is charted as Temple Pit; the town becomes Henley-on-Thames Haven, with Hambleden-under-Sea and Fingest-under-Sea up the side valleys.

Every sounding on the sheet is a real land height turned upside down, so the channels follow the true shape of the valleys. It’s a chart for rowers, for anyone who has walked the Thames Path, and for sailors who live a long way from the sea.
