Holton Pit is a 1.6-hectare (4.0-acre) geological Site of Special Scientific Interest east of Halesworth in Suffolk. [1] [2] It is a Geological Conservation Review site. [3]

This was thought to be the only site known to show the sequence of the early Pleistocene Westleton Beds overlain by "quarttzose gravels" deposited by the proto-Thames river as the Kesgrave Sands & Gravels. The "quartzose gravels" are now thought most likely to be Anglian glacial outwash. The Westleton Beds mainly consist of sand but were quarried here for gravels that were a coastal gravel accumulation, especially gravels washed into large channels, and the site is close to their known inland boundary and throws light on their spatial limits. [4]

Footpaths from Holton go through the site.
