The London Road runs along a valley bottom, but where is or whatever
happened to the river?
There are many coombs or dry valleys across the Downs that were cut
during the last ice age. When the ice retreated the glacial rivers
ceased to flow.
But the valley of the London Road has an intermittent river, one that
flows when the winter rainfall is especially heavy. The water table
in the chalk of the Downs rises to the surface and a stream flows down
the London Road. It last happend in the very wet winter of 1999/2000.
Despite our modern sewerage system and water pumping stations out on
the Downs a steam flowed down the London Road during the wettest winter
