Wiveton Downs is a 28.9-hectare (71-acre) biological and geological Site of Special Scientific Interest at Wiveton, west of Sheringham in the English county of Norfolk.[1][2] Part of it is a Geological Conservation Review site,[3][4] and an area of 6.5-hectare (16-acre) is a Local Nature Reserve.[5][6] It is in the Norfolk Coast Area of Outstanding Natural Beauty.[7]
The site is a classic example of an esker, a glacial crevasse which has been filled in until it forms a narrow winding ridge. It is considered very important for teaching, research and demonstration.[8]
