The evaluation comprised three trenches; Trench 1 to the west of the corridor in GA1, with Trenches 2 and 3 in GA2. The trenches were laid out using a dGPS with an accuracy of �10mm. Excavation of the trenches was carried out using a mechanical excavator equipped with a toothless ditching bucket under direct archaeological supervision. Soil was removed in level spits of no more than 0.2m until either the top of the first archaeological horizon or undisturbed natural was reached. The resulting surface was inspected for archaeological remains. All features revealed were excavated to establish their depth and profile. The trial trenches revealed that there is little archaeological potential in the areas evaluated. The geophysical anomalies 4000 and 4007, in Trenches 1 and 3 respectively, have been shown to be plough furrows. The anomaly, 4006, in Trench 2 may have been caused by the thin patches of iron panning material identified. The trail trenching has confirmed the results of the geophysical survey; the survey appears to have been effective in identifying shallow anthropogenic features, suggesting that the results provide a good indication of the archaeological potential of the survey areas.
