Hawkstor Pit is an important palynological site for interpreting Late Quaternary environmental history in upland south-west England. It provides a detailed stratigraphic and chronological record of vegetation and climatic changes during the Devensian Late-glacial. The sequence of deposits, dating from about 13,000 before present (BP), includes interstadial organic sediments and stadial solifluction gravels with cryoturbation structures. The pollen and plant macrofossil stratigraphy has been studied in detail and pollen assemblage zones radiocarbon-dated. Hawkstor Pit also includes a partial record of early and mid-Flandrian environmental changes.
