On Friday we begin our journey meeting at Magdalen Bridge in Oxford to walk in silence to the Thames-Isis to collect water which we will carry to Bonn.
During our research we were exhilarated to find that the Thames connection to the Rhine goes back to glacial times, when Britain was connected to Europe. During this period The Thames was a tributary of the River Rhine, probably flowing along a line slightly north of it current course through the Vale of St Albans, through Essex and across the low lying lands of the Rhine Estuary. In about 12,000 BC, temperatures slowly started to rise again, ice began to melt, sea levels rose and engulfed these low lying lands leaving a series of small marshy islands and a low ridge of firmer ground in the area we now call the Dogger Bank. In about 6,500 BC, the water of the North Sea finally rose over the Dogger Bank and broke through the remaining and broke through the remaining ridge of land between Kent and Northern France. The Straits of Dover were created and Britain became an island.
