Sundon Chalk Quarry, Geological Site of Special Scientific Interest in Upper Sundon, United Kingdom.
The 26.2-hectare quarry contains diverse habitats including fens, lakes, chalk grassland, scrub, and woodland across its multiple excavation pits.
The quarry supplied chalk and marl to Sundon cement works from 1899 until 1976, playing an essential role in local industrial development.
Scientists and researchers frequently visit the quarry to study sedimentary processes, chalk formation, and conduct geological research initiatives.
While privately owned, the quarry offers free public access through the Chiltern Way footpath, allowing visitors to explore its natural features.
The site houses the largest colony of Chiltern gentian in England and supports twenty-one butterfly species, including the Adonis blue butterfly.
