Banks forming a roughly rectilinear enclosure northwest of Horner Gate were noted on aerial photographs taken in the 1970s. [1-3] There is nothing to be seen on the ground to sustain the aerial photographs mark of an enclosure as mentioned above. There has been peat cutting on the hill and the mark may be associated with this, though no complete rectilinear turf tye is evident. [4] A study of the archaeology and history of peat exploitation on Exmoor’s moorlands provides additional background on the practice and sites. [5]
