Excavation of this site commenced in 1983; as work progressed, hitherto unsuspected features were foun spreao dt d some distanc weste th o ,et toward henge sth e (Barclay 1984). The henge at Balfarg was identified first by Steer on aerial photographs taken in 1947. Atkinson (1952) in his plot of the cropmarks, showed one entrance, the south-west with two opposing ditch- butts dottee H .suggeste a n di south-ease ditchde th linth r f t visibleo ,e fo whicc no th s ar tn eo h wa photographs available to him or indeed on subsequent photographs. When excavated it was found that an area of different soils, in which the observation of features was even more difficult than elsewhere on the site (Mercer 1981, 66) occupied this southern zone. The linear feature was located within this area which was excavated and recorded as a ditch.
