The Ercall, sometimes known as Ercall Hill, is a small hill in the ceremonial county of Shropshire, England. It is located between The Wrekin and Wellington, in the Telford & Wrekin borough. It is regarded as an internationally important geological site, which is part of The Wrekin and The Ercall Site of Special Scientific Interest (SSSI). The hill is managed by Shropshire Wildlife Trust. The site includes 540 million year old ripple beds and ancient pre-Cambrian lava flows in exposed quarries. [1] Quartzite from the neighbouring Wrekin is also visible. The Ercall bears the marks of extensive quarrying, although the quarries are now disused, safe and open to the public.
