2 Map Introduction: Map This map section covers part of the south coast of, including the head of the causeway which links the island to Eriskay. It extends from South Glen Dale to Taobh a'caolas. There is modern settlement within the coastal zone at Taobh a'caolas and some more isolated settlement at South Glen Dale. The modern road runs close to the coast for most of this section. There is a modern harbour at Taobh a' Caolas. A total of 7 sites were recorded in this section, of which were previously known. All but one represent domestic, agricultural/pastoral or maritime sites of 8th-st C date. The exception is an area with numerous small coastal exposures containing probable midden-type deposits at South Glen Dale (SU66). This site lies in an area where previous work found traces of both Beaker-period and post-medieval remains. The deposits which are currently visible contained no diagnostic artefacts and could not be dated. The foreshore in this area is comprised mainly of sand, with three small occurrences of rock platform. The hinterland has drift deposits covering visible rock. The majority of the coast edge is classified as stable, with the exception of a short stretch of eroding shoreline around Taobh a'caolas. 97

5 Hinterland Geology & Coastal Geomorphology Map. Bagh Mor to Eriskay causeway NF 7946 to NF km Mainly Sand Coast edge <5m Drift on visible rock The hinterland is rock (Lewisian gneiss) mantled by drift that provides a thin poorly developed soil/peat and Calluna (heather) vegetation. The foreshore is predominantly sand (00% cover) with a low cliff.. Jetty to Cul phort NF to NF km Mainly Sand Coast edge <5m Drift on visible rock A rock platform occurs at the headland at both sides of Babh Shaltabhaig. The stretch of coastline immediately west and east of the jetty are everywhere characterised by a thin cover of drift resting on gneiss bedrock. The coastal edge is defined by a degraded cliff line cut in drift as a result of the 005 hurricane. The coastline is generally bare of sand with the exception of the Bay at NF 7784 and is characterised mostly by gneiss boulder accumulations. In many areas the erosive effects of storm wave action has been the deposition of shingle washover plumes well above the reach of present normal wave activity. At NF an arcuate shingle ridge has been formed on the drift surface. Sand deposition is evident on the upper slopes of the hinterland up to 3 m above HWM with a distribution up to 5 m inland. In places, boulders that constitute part of the normal coastal defences have been moved landward by storm wave action. 00

7 Erosion Class. Bagh Mor to Eriskay causeway NF 7946 to NF km Stable Along the eastern slopes of Bagh Mor the drift and peat mantled slopes above the foreshore are characterised by recent erosion and a degraded cliffline. By contrast between the eastern shore of Bagh Mor and the causeway, the coastal edge is represented by drift and peat-covered rock slopes that display little evidence of erosion perhaps due to the location of this coastal area to the east of the Eriskay causeway. Map. Jetty to Cul Port NF to NF km Stable/Eroding Approximately 00m landward of the jetty in the inner embayment there lies the remains of a small fishing boat thrown landward and upward by the storm waves. At Cul Port storm erosion has locally exposed Holocene dune sands resting on top of drift. The distribution of flotsam at Loch Bhruga and Cul Port show that both lochs were inundated by storm waves during January 005. The coastline displays storm damage at several places and numerous examples exist of sections of the coastal road that has been removed by wave action and backfilled with rubble. The coastal edge can be defined as subject to active retreat almost everywhere. In many areas the erosive effects of storm wave action has been the deposition of banks of shingle well above the reach of present normal wave activity. In places, boulders that constitute part of the normal coastal defences have been moved landward by storm wave action. 0
