Seale Chalk Pit

Seale Chalk Pit is a chalk quarry in Surrey positioned on the southern flank of the Hog's Back. The site exposes distinct layers of sedimentary rock that record the geological boundary between Mesozoic rocks of the Weald and Tertiary sediments of the London Basin.

The quarry operated as a working site until the 1930s, playing a role in mineral extraction across the Hog's Back region. After extraction ceased, the site transformed into a location supporting specialized plant and insect communities.

Scientists and researchers study the site to understand the separation between the Mesozoic rocks of the Weald and Tertiary sediments of the London Basin.

Visiting requires advance permission from Surrey Wildlife Trust, as entry is restricted to protect the site's ecological value. Plan to contact the organization before arranging a visit to check access conditions.

The former quarry now supports over 130 species of chalk grassland plants, including orchids, cowslips, and specialized butterfly populations. This flourishing diversity emerged naturally once extraction activities ceased.
