Grouse Hall: Floodplain Reconnection, Hutton Le Hole, North Yorkshire: A Report on an Archaeological Watching Brief

The Yorkshire Wildlife Trust commissioned LS Archaeology to undertake an archaeological watching brief on land to the southwest of Grouse Hall, Kirkbymoorside, Hutton Le Hole, North Yorkshire (NGR: SE 68928 90207) (Figure 1). The fieldwork was undertaken at the end of August, and the start of September 2024, and monitoring was undertaken during ground stripping for scrapes and a ridge associated with a flood regeneration scheme. The site is situated within the North York Moors National Park in an area with significant prehistoric archaeological remains. Historical evidence suggests that the site containeda large number of worked flint tools and debitage dating from the Mesolithic to the Bronze Age. The watching brief identified prehistoric and Roman British archaeological features and residual flint across approximately 16 acres. The residual domestic flint assemblage, spanning multiple periods, consistently features specific raw materials and shows systematic core preparation. This pattern likely results from the site's distance from major raw material sources, requiring a more purposeful and efficient use of materials. Although the assemblage does not offer conclusive evidence of a prehistoric settlement, it also is not simply a typical background scatter. The extensive working of flint debitage and cores indicates that a settlement could be nearby or that undisturbed archaeological deposits are still present on the site. Radiocarbon dating has shown that the site underwent episodic prehistoric use from the Mesolithic to the Early Bronze Age, with dated fire pits and hearths confirming activity across these periods. Some further features remain less securely dated and can only be attributed to a broad prehistoric horizon on contextual grounds. The principal later archaeological deposits relate to burning and industrial metalworking activities, provisionally dated to the Roman period. The material is comparable in shape and microscopic structure to Romano-British slags from South Yorkshire, including sites associated with military establishments. The preserved material, including a field forge with zoned smithing and smelting areas, indicates Romano-British ironworking technology. The Romano-British activity may be connected to the Iron Age-Romano-British settlement at Gillamoor, approximately 700m to the west and southwest. Considering the narrow width of the River Dove, a crossing point could have been nearby. Furthermore, Cawthorne military camp is situated only 5.6 miles to the east. The Grouse Hall site offers significant evidence of multiphase activity, including early prehistoric exploitation during the Mesolithic, Neolithic, and Early Bronze Age periods, as well as later ironworking in the Roman period. The excavated areas represent only discrete portions of the land fronting the River Dove; it's possible that other archaeological evidence, including settlement remains, survives in adjacent areas of the landscape.
