Cloford Quarry, Geological conservation site in Somerset, England
Cloford Quarry is a protected geological conservation site in Somerset containing significant rock formations and sediments from multiple geological periods, including Triassic and Jurassic layers spread across approximately 39 hectares. The site displays complex geological structures that reveal Earth's history through these distinct stratigraphic layers.
The site was designated as a Site of Special Scientific Interest by Natural England in 1994 to protect its geological features for research and education. This recognition acknowledged the scientific value of the rock formations for understanding ancient sedimentary processes.
The quarry became known beyond geology when it served as a filming location for Doctor Who episodes, where it represented the alien planet Lakertya.
Access to the site requires permission as it remains private property, so visitors need to contact the management in advance to arrange entry authorization. Plan ahead to secure the necessary approval before visiting.
The quarry contains rare fissures within Carboniferous limestone that preserve sediments spanning six different geological ages, including the Rhaetic and Bathonian periods. These natural cracks offer an unusually complete window into millions of years of Earth's history concentrated in one location.
