The Wash. That "proto-Soar" river was also modified by glaciation, but in that case by the later Wolstonian ice advance. Those western and eastern sections never linked up to form a "Bytham river". Another study asserted that the refutation of the existence of the Bytham is itself "contradicted by an abundance of evidence", and that sand and gravel deposits of the proto-Soar in Leicestershire could "only have been emplaced by a river flowing eastward across East Anglia" (ie, according to this study, by a large, pre-Anglian river, the Bytham).
