Geology of Wales - Quaternary

Quaternary

The landscape of Wales has assumed its present shape over the last 2.6 million years i.e. during the Quaternary period which reaches to the present day. Icesheets and valley glaciers which developed during a series of ice ages have significantly altered a landscape which had developed as rivers drained a tilted upland surface which is thought to have emerged from beneath the sea during earlier Cainozoic times.
