The geodiversity of the Brecks underpins much of the area’s rich heritage of landscape, biodiversity and cultural features. This project, one of four run by Tim Holt-Wilson of Norfolk Geodiversity Partnership ran a sequence of three day schools to communicate the Ice Age heritage of the Brecks. There are many landforms, paleolithic archaeological features and fossil biodiversity to be discovered by the untrained eye. Aiming to bring these schools to an audience of 90 participants from the local area, as well as visitors, these event proved very popular, with 92 attending in total.
Each day school began in Thetford, with an introductory presentation providing some background information on the Brecks geomorphology and Ice Age processes. Then participants boarded a coach to commence visits to a variety of sites to witness how the ice has sculpted and affected the landscape that we see today. John Lord, a renowned flint expert and skilled knapper, was also enlisted to demonstrate how flint was manipulated by early humans in the area, examples of which can still be found scattered across the Brecks.
The participants were taken to sites including Beeches Pit, a Hoxnian interglacial site at West Stow, Grimes Graves, which has evidence of periglacial soil processes linked to differences in biodiversity seen today and Lynford Lakes, a Neanderthal paleolithic site. Trips were also made to Knettishall heath which again shows periglacial soil processes from pre-Anglia river sediments, the ‘Devil’s Punchbowl’, a fluctuating mere, and Frost’s Common where there is evidence of periglacial ground-ice depressions. The lectures and field visits provided an improved understanding of the evolution of the physical environment that exists today in the Brecks.
