"A north-south valley west of the Malverns contains a variety of Pleistocene deposits, largely hidden by late Pleistocene solifluxion. Around Eastnor is a stony clay attributed to an ice-tongue that crossed the Malvern hills from the Severn valley. Various sediments north of Eastnor are thought to have been laid down in a lake held up by this ice-tongue and fed by a stream diverted across the hills north of the Malverns by the main Severn valley glacier. The Upleadon gravels south of Eastnor are attributed to water released from the lake when the ice-tungue melted. Both lake and glacier are correlated with the Woolridge gravels and hence with the penultimate glaciation."
