The stratigraphy of the two pits and the three boreholes from the site are similar (Aitken, 1991) and is summarised in [[Media:P915324.png|P915324]]. Both pits contained an organic unit at least 10 to 20 cm thick, overlying fine-grained silty sand and overlain by 4.0 to 4.5 m of clay and grey pebbly sands. The organic remains in Pit 1 (NJ 8002 1597) comprised twigs, branches, bark, leaves and seeds in a matrix of grey, silty clay. The upper part of the organic unit in Pit 2 (NJ 8004 1603) contained a higher proportion of organic matter. It comprised woody peat, with thin sand laminations that contained plant macrofossils and insect fragments, again within a grey, silty clay matrix. These organic sediments are interpreted as part of a late Holocene channel fill succession (Aitken, 1991).

Although only bulk samples of the organic remains were obtained, pollen analysis, and <sup>14</sup>C dating of the organic unit was undertaken. Its pollen content was similar in both pits (see table below) and indicated sparse vegetation. Non-arboreal pollen is dominant, particularly Gramineae and Cyperaceae, and to a lesser extent Ericales. However, ''Betula, Alnus ''and ''Corylus/Myrica ''were present in significant proportions. The environment was, therefore, dominated by grass with some heathland, perhaps on the valley sides. Cyperaceae, and possibly ''Myrica'', probably grew in the silted, abandoned channel, while some stands of birch, alder and possibly hazel woodland were present locally (Aitken, 1991).

A single sample from Pit 2 was separated into plant macrofossil and organic fractions for radiocarbon dating. The respective fractions yielded dates of 3855 ± 50 <sup>14</sup>C years BP (SRR–3718 i) and 4120 ± 50 <sup>14</sup>C years BP (SRR–3718 ii) (table below). The slight discrepancy between the two ages is attributed to the presence of reworked older organic residues in the silt.
