A large, grassed over spoil heap probably containing waste from the adjacent Grange Colliery pit which closed in 1963. The 1893 OS map marks the position of old shafts indicating earlier mining activity within the area. The 1st Edition OS map of 1854 shows some irregularly shaped fields, probably the result of piecemeal enclosure upon the disparkment of Kimberworth Deer Park. Significant legibility of the previous landscape.
