at the eastern end. The yellowish-brown gravel and clayey silt
ploughsoil (C1123) was found to be c.0.30-0.35m deep. This
overlay the natural subsoil which consisted of an homogenous
orangish-brown gravel and clayey silt which became gradually
more grey in colour towards the eastern end of the trench
(C1124).
A single feature was identified within Intervention 31 and
allocated F33, which appeared as a crescentic deposit of light
olive brown sandy clay (Figure 84). The deposit measured
2.20m in length by 0.60m in width. Upon excavation, F33

proved to have a shallow cut with gently sloping sides and a concave base and measured c.0.10m deep (Figure
85). The feature had been backfilled once with C1221. The backfill consisted of a sterile pale olive sand with
only rare mixed pebble inclusions and very rare charcoal flecks. F33 was interpreted as a small irregular pit;
no dateable material was recovered during excavation.
8.2.26 Intervention 32
Intervention 32 was located in the southwestern corner of Zone
A and measured 100m x 4m (see Figure 36). The trench was
positioned in order to contact a curvilinear anomaly detected
during the magnetometer area survey (Intervention 4, F13),
although it was not encountered archaeologically. The trench
was machine excavated and was orientated east-west (Plate 39).
The ground within the area of the trench was 40.80m AOD.
The yellowish-brown gravel and clayey silt ploughsoil (C1123)
was found to be c.0.30m deep and overlay a natural subsoil
which consisted of an homogenous orangish-brown gravel and
clayey silt with broad bands of cleaner greyish-brown clayey
silt towards the western end of the trench (C1124).

No features were defined within Intervention 32.
8.2.27 Intervention 33
Intervention 33 was situated 29.20m to the north of Intervention
33, measured 100m x 4m and was designed to investigate and
intersect several geophysical anomalies (Intervention 4, part of
F7, F8 and F10, Intervention 5, F37) (see Figure 36). The
trench was machine-excavated and was orientated north-south
(Plate 40). Ground surface within the area of the trench was
40.90m AOD. Ploughsoil consisted of a yellowish-brown
gravel and clayey silt (C1123) which was a consistent 0.30-
