NEWS UPDATE... Historic Environment Record Review Information on all the known archaeological sites and important buildings in the National Park is maintained in the form of a detailed index, known as the Historic Environment Record (HER), which contains over 20,000 records. The distribution of sites and finds can then be mapped very simply on top of the most up-to-date digital Ordnance Survey maps on the computer. A review of the current record system has recently been completed and work is now underway to upgrade and modernise the record system in order to improve its efficiency and meet modern standards. It is hoped that, in due course, this modernisation will eventually enable the HER to be accessible via the internet. If you are interested in consulting this information at present, please contact the Authority’s Archaeological Conservation Officers to arrange an appointment. INVESTIGATION AT BOLTBY SCAR The initial investigation of the Iron Age Promontory Fort at edge of the Hambleton Hills until the 6th century AD, much Boltby Scar (SE 5060 8563) took place in September 2009 as later than previously thought. Before this time, back to when the part of the Lime & Ice project. ditch was first cut, the environmental evidence suggests that the Boltby Scar is a very small promontory fort (only 1.16 hectares area was predominantly open pasture with little tree cover. This in size) which lies in an important archaeological landscape was replaced by heathland from the 6th century AD which is which has produced masses of evidence for the activities of thought to have developed due to soil deterioration, producing our prehistoric ancestors. There is a second (much larger – a more acidic environment. The most recent phase indicates actually the largest in the north of England) promontory fort at a return to grassland. The level of environmental preservation Roulston Scar, 4 km to the south, apparently linked to Boltby and survival encountered within the ditch deposits was quite by the construction of a linear earthwork boundary known unanticipated, but the rapid rate at which the organic fills in as the Cleave Dyke, as well as large numbers of earlier burial the top of the ditch decayed on exposure to the atmosphere monuments (round emphasized barrows) from the the fragility of Bronze Age. environmental archaeological Promontory forts evidence in the are a type of hillfort context of climate in which strong change. natural features – particularly Despite the promontories of survival of such higher ground – good environmental are adapted for evidence in the defence by the upper fill of the ditch, construction of the number of finds earth or stone recovered from the ramparts and ditch sections was ditches to cut negligible.

This is being accomplished by providing practical assistance to landowners to help control a wide range of management problems, including bracken and scrub growth, animal burrows and other forms of erosion. About 42% (371) of the National Park’s 839 Scheduled Monuments were indicated to be at high or medium risk in English Heritage’s Heritage at Risk statistics released in 2009. Although the percentage of sites At Risk seems to be quite large, the risk status for many sites is high simply because they have not been formally inspected in recent years, a matter complicated by the sheer number of sites within the National Park – nearly a third of all Scheduled Monuments within the Yorkshire and Humber Region lie within the North York Moors. Initial work has included a series of bracken control agreements with the National Trust and Forestry Commission. Ongoing work includes commissioning archaeological consultants to make site visits to draw up management plans for further Swarth Howe Bronze Age burial mound overgrown with gorse monuments and, more specifically, to prepare for the re-erection of the fallen Wade’s Standing Stone at East Barnby. Current phases of the Scheme include the conclusion of management agreements with landowners, together with the carrying out of ground works this summer. The National Park’s Archaeology Volunteers group have been playing their part in this process by monitoring and recording the current condition of monuments, after training last year to recognise and record potential threats.
