A New Glacial Chronology for East Yorkshire?
Recent Work on Flamborough Head
and in Holderness


Dr Rodger Connell
University of Hull


The Dimlington site in southern Holderness was designated the type site for the period of most extensive glaciation in Britain during the last cold stage in 1984. This Dimlington Stadial was believed to be younger than ~20,000 years, quite a surprise when the original radiocarbon dates were published in 1969! In recent years dating of both organic and inorganic sediments (by both Radiocarbon (C14) and Optically Stimulated Luminescence (OSL) techniques) has suggested the last ice sheet may have grown earlier in Britain and been much more dynamic. This talk will focus on recent work by myself and colleagues from the Hull Geological Society on overlooked sites on Flamborough Head (last recorded by George Lamplugh in the 1890s) and in Holderness (some last documented by W.S. Bisat in the 1930s). This work has been supported by Professor Mark Bateman (Sheffield University) with OSL age estimates at sites on Flamborough Head. From this work a new chronology for the glacial sequence in East Yorkshire is emerging suggesting a more complex and earlier series of advances of the North Sea Lobe of the last ice sheet.

• Roundhay Park - A Walk Back in Time •


Guided walks around the Geology Trail in Roundhay Park are held during the year. The walks are led by the geologist who created the trail and, making regular stops, take about 2.5 hours and cover a distance of around 3 km. They are suitable for people of any age - no previous knowledge is required!

For further information contact Bill Fraser on 0113 2608764 or email w.fraser@btinternet.com

A booklet, 'Roundhay Park - A Walk Back in Time' (24 pages, full colour) which describes the marked geology trail in Roundhay Park is available. It is a combined effort between LGA members, who provided the idea and the content, and Friends of Roundhay Park, who provided the help on the ground. It can be found in various local outlets for £1.00 or by post. Contact Bill Fraser on 0113 2608764 or email w.fraser@btinternet.com for further details.
