Royston Road Gravel Pit, WENDENS AMBO, Uttlesford District, TL49473633, Potential Local Geological Site
Site name: Royston Road Gravel Pit
Grid reference: TL 4947 3633
Brief description of site:
Pit cut into the hillside exposing glacial gravel made up almost entirely of chalk pebbles. The faces show solution ‘pipes’ and ice disturbance structures. The pit is very small with only 2.5 metre high faces.
The ‘pipes’ are infilled with darker gravel and are due to localised solution of the chalk pebbles (See Sumbler (1996) for an example of this phenomenon in Oxfordshire). The pipes are analogous to the solution pipes found in the Chalk.
The pit is on private land. Access is only permitted with permission of the land owner.
