MDE11702 - Modern drainage system on Butter Hill (Monument)
Please read the caveat document.
Type and Period (3)
- None recorded
SS 705 451. Low banks forming derelict fields seen by McDonnell  on aerial photographs . There is no trace of any fields in the area indicated by McDonnell. The area, shown as open moorland on the 1904 Ordnance Survey map  has been improved and is now permanent pasture. The features seen by McDonnell and interpreted as banks and fields appear to be a drainage system formed by combination of natural and artificial drainage channels. The natural gulleys, all dry, are rather sinuous and broad (about 5 metres wide and 1 metre deep) and appear to have been artificially straightened or improved to facilitate drainage. The new field drains are evident as very low, long banks which cover drainage pipes. [3,4] The features identified by McDonnell were visible on many of the aerial photographs available to the NMP survey, and in the opinion of this authority it can be confirmed that the features do not form banks and fields boundaries. However, it is also the opinion of this authority that not all of the earthworks McDonnell recorded were constructed as artificial drainage channels, as summarised by the above authority. The curvilinear feature centred on SS 7048 4512 is possibly a footpath which may connects with a hollow way at its northen end, at SS 7045 4526. [5,6] This record was enhanced as part of the National Record of the Historic Environment to Exmoor National Park Historic Environment Record data transfer project.
