The trial trenching comprised the excavation and recording of ten linear trenches each measuring approximately 30m x 2m in plan (Fig. 2). The positions were proposed in the site-specific WSI in order to target specific anomalies with archaeological potential detected by the earlier geophysical survey. The trenches were excavated using a mechanical excavator fitted with a wide, smooth-bladed bucket, working under direct archaeological supervision. The trenches were excavated down to the first significant archaeological horizon and then hand-cleaned prior to any archaeological features being investigated and examined through hand excavation. For reasons of expediency, the mechanical excavator was subsequently employed under close supervision in order to machine-excavate some larger features down to a level which would enable subsequent hand-cleaning and recording. Standard Humber Field Archaeology recording procedures were used throughout; each identified feature was allocated a context number, with written descriptions recorded on pro forma sheets. Plans and sections were drawn to scale on pre-printed permatrace sheets. A photographic record was maintained using a high-resolution digital camera. The locations of the trenches and the level of the features were surveyed relative to the Ordnance Survey National Grid and Ordnance Datum respectively, using survey-grade GPS equipment. Finds encountered were recorded to professional standards using recognised procedures and numbering systems compatible with the accessioning system employed by the recipient museums service (in this case the East Riding of Yorkshire Museums Service). Finds recovered from each feature were labelled accordingly, with those of individual interest, other than pottery or animal bone, being allocated Recorded Find (RF) numbers. One environmental soil sample was taken from a targeted feature for its environmental potential. In June 2021, archaeological evaluation by trial excavation was undertaken by Humber Field Archaeology in the Outgang extension of the Newport Road Quarry, a site of permitted extraction of sand and gravel by Breedon (Northern) Ltd, which lies south-west of North Cave village, East Riding of Yorkshire. Ten 30m long trenches were excavated in the north-western corner of the extraction area in order to investigate a number of anomalies representing potential archaeological remains, revealed by an earlier geophysical survey, (Roseveare and Smith, Sept 2019).
