Chains (geological site)
It is a Geological Conservation Review site, recognised as being nationally important for its south-western lowland heath communities and for transitions from ancient semi-natural woodland through upland heath to blanket mire. The Chains provides a palynological record of a mid to late Flandrian vegetation history on Exmoor. The pollen sequence in the peat is calibrated by radiocarbon dating.
On the Chains above Simonsbath is a 3 acres (1.2 ha) reservoir known as Pinkery Pond. It was formed by John Knight and his son in the 19th century by damming the River Barle. The pond was originally intended to be 7 acres (2.8 ha). Its purpose is unknown but close to the pond are the remains of a small canal.
