• Berneray/Beàrnaraigh Island centre (NF 910 820) Distance c. 20km • Baleshare/Baile Sear Island centre (NF 790 610) Distance c. 27km • North Uist, west coast North causeway (NF 907 795) - South causeway (NF 844 592) Distance c. 148km • Vallay/Bhalaigh Island centre (NF 778 765) Distance c. 16km 2.4.3 The archaeological surveys were undertaken following procedures outlined in Historic Scotland’s Procedure document. Two teams of archaeologists working in pairs surveyed the study areas described above. North Uist and the islands presented no problems in terms of access. 2.4.4 Information on the general condition of existing and newly recorded archaeological sites was recorded onto coastal zone assessment sheets in accordance with HS APP4, and included details on dune blow-out points and regions of deflation. Known archaeological sites and monuments within the survey transect were visited wherever possible. Each site was allocated an identifying location number. The location of each site was established using a GS50 Global Positioning System (GPS) instrument that provided a ten-figure grid reference with >1m accuracy. A full photographic record will be maintained. The survey did not include any invasive archaeological investigation, nor any detailed emergency recording, sampling or retrieval of artefactual material. 2.4.5 During the field survey information on the character and erosion of the coastline was collected. This information was provided to the Project Geomorphologist in order that he could undertake targeted site visits, check the findings of any eroding archaeological sites and assess what mechanisms were leading to erosion of those sites. 2.5 Coastal geology and geomorphology 2.5.1 A comprehensive review of the available documentary and cartographic sources covering the coastal geology/geomorphology and erosion criteria within the study area was undertaken by Dr Michael Cressey, CFA’s Environmental Scientist. Targeted site visits were carried out for field inspection following the walkover survey. Field notes, digital photographs and other topographical information were added to the coastal geomorphology maps. UISN/1051/0 7 CFA
2.5.2 The GIS database incorporates the coastal geology and geomorphology information and was placed onto colour-coded digital base-maps. 2.6 Report Format 2.6.1 In this report we use the term shoreline to refer to the distinct boundary between land and sea that changes with the tides. A coastal unit defines the areas between numbered cut-off points that demarcate individual sections of coastline which has been classified according to its eroding, stable or accreting status. 2.6.2 The results are presented sequentially for each coastal unit and follow the standard format (Ashmore 1994). Elements include an introductory section followed by sections detailing the coastal geology/morphology, coastal erosion and archaeological gazetteer and maps. These are followed by a section incorporating results and observations. This is followed by a list of references and appendices. 2.6.3 Each survey area is accompanied by three individual maps. These maps contain data on the Hinterland Geology and Coastal Geomorphology, Erosion Class, and Built Heritage and Archaeology. The gazetteer entries include the following categories: Hinterland Geology and Coastal Geomorphology Identification number and name of coastal section National grid reference Distance of coastal section Typical deposit type on the foreshore Height of cliff Hinterland geomorphology Description Erosion Identification number and name of coastal section National grid reference Distance of coastal section Type of erosion present Description Built Heritage and Archaeology Identification number and coastal section National grid reference National Sites and Monument Record Number Site name or type Condition Period/date Recommendation UISN/1051/0 8 CFA
