“The Geological History of the River Lune from the Ice Age until the present day”
Presenter: Paul Carling
This talk will explore how we can decypher the history of rivers from the evidence in the landscape. The river courses we see today are not static but have changed through time and will continue to change, through natural processes, if but slowly when seen from a human perspective.
The major river valleys of Lakeland and the Pennines we see today, probably were recognizable just before the Ice Age commenced. This talk follows the physical evolution of the River Lune as it was affected by a covering of glacial ice. At the end of the Ice Age, the Lune was a river draining meltwater from the retreating ice front. The land surface began to rebound upwards as the weight of ice was removed, at the same time as the sea level rose. These two processes led to waves of incision into the riverbed forming river terraces (benches) either side of the course as far as Lancaster. Dating when the sediment in the terraces was deposited allows a timescale to be produced for the river’s history.
The river history continues due to present-day climate change.
