The field system consists of three roughly parallel divisions, spaced about 35 metres apart, extending approximately 280 metres in a northwest to southeast direction. They are detectable only as cropmarks, the phenomenon whereby buried features affect the growth of crops above them, producing subtle differences in colour or height that reveal themselves to an aerial observer but leave no surface trace for a walker passing through.

The boundaries came to light on 16 July 1971, when two aerial photographs taken as part of the Cambridge University Collection of Aerial Photography captured not only the field system but also a separate enclosure lying roughly 50 metres to the north. Cropmarks of this kind are often associated with earlier land organisation, and the regular spacing here suggests deliberate, planned division of agricultural ground at some point in the past. The enclosure nearby hints at a broader pattern of activity in the area, though the photographs alone cannot settle questions of date or function. The two features were recorded together, their relationship suggested by proximity rather than confirmed by excavation.
