At this site heavily cemented Pleistocene terrace gravels of the River Cary have yielded an abundant freshwater and terrestrial molluscanfauna. The fauna has an interglacial aspect, and includes Corbicula fluminalis and Pisidium clessini. This site is of critical importance as the keystone of the Pleistocene stratigraphy of southern Somerset, and as a freshwater facies-equivalent of the Burtle Beds.
