gravel and pebble inclusions. F19 is a continuation of F13, which was identified in Intervention 18 and was
interpreted as a sink hole and was encountered during the magnetometer survey (Intervention 4, F29).
F22 was situated c.1.5m from the southern end of Intervention
23 and was situated against, and continued beyond, the eastern
edge of excavation (Plate 27). It appeared as a possibly circular
deposit of gravel-rich brown clayey silt measuring 1.5m long x
0.89m wide. The available area of the feature was excavated,
and it proved to be a shallow scoop with gently sloping sides
and a concave base (Figure 62). The feature had been
backfilled once with C1200, which consisted of a sterile brown
clayey-silt with high percentages of gravel inclusions (80%).
The feature was no greater than 0.22m in depth, appeared as a
truncated pit or posthole and no dateable material was
recovered.

8.2.18 Intervention 24
Intervention 24 was located towards the southern boundary of
Zone C (see Figure 36) and measured 50m x 8m, orientated
east-west (Plate 28). Ground level sloped down slightly from
c.42.80m AOD at eastern end of the trench to c.42.60m AOD at
the western end. The dark yellowish-brown ploughsoil (C1123)
was found to be c.0.30m in depth throughout the trench and
overlay an homogenous orangish-brown gravel and clayey silt
subsoil (C1124).
A single feature (F23) was identified within Intervention 24 and
was located c.7.00m from the eastern end of the trench (Figure
63). F23 was situated against the southern limit of the intervention and continued beyond it. Where visible,
the feature appeared to be a possible sub-circular feature measuring c.0.50m in diameter. The entire available
area of the feature was excavated, where it proved to be 0.31m deep with steep sides and a flat base backfilled
once with C1201 (Figure 64). C1201 consisted of a friable dark yellowish-brown sandy clay with frequent
gravel and pebble inclusions. The feature appeared to be a
small pit, but no dateable material was recovered from C1201.

8.2.19 Intervention 25
Intervention 25 was situated in the southern area of Zone B (see
Figure 36) and measured 100m x 4m, being orientated northsouth
(Plate 29). Ground surface was fairly level throughout the
trench at c.42.20m AOD, sloping down at the southern end to
c.41.95m AOD. The dark yellowish-brown ploughsoil (C1123)
