Watermill Cove

Watermill Cove is on the north–west coast of St Mary’s, Isles of Scilly. The cove is within an Area of Outstanding Beauty, is a Geological Conservation Review site and was designated a Site of Special Scientific Interest (SSSI) in 1996. The 0.48 hectares (1.2 acres) site is notified for a succession of Quaternary exposures in the cliff and from sea level to the top of the cliff (oldest to youngest) the succession shows:

• head deposits
• organic silts and sands
• head deposits of the Late Devensian with microscopic remains of plants and pollen and dated to circa 30 000 years before present. The remains indicate an Arctic tundra climate
• raised beach deposits, a storm beach of the Late Ipswichian interglacial 130,000 years ago and ended about 114,000 years ago.^[1]
