A new exposure of Quaternary deposits at Poets' Corner Yard, Westminster Abbey, Central London

Work prior to the construction of a tower for access to the triforium, Westminster Abbey, provided temporary exposures of Quaternary deposits. Two units were seen: the Shepperton Gravel Member, and overlying Poets' Corner Sand (new name). Distinctive features of the Poets' Corner Sand are described. The age of the base of the Poets' Corner Sand by optical dating is 15 000 ± 1000 years BP. The foundations of the Abbey are briefly described.
