6. SURVEY MAPS OF THE RIVER CLYDE

CLYDE MAP 1: CRAIGENDORAN PIERS to ARDMORE ISLAND Hinterland Geology and Coastal Geomorphology: Undifferentiated glacial tilloverlain by marine deposits dominate the hinterland. Remnants of a raised shorelineare also present. The coastline is irregular and wide expanses of mudflats are exposeddown to the MLWMST. Ardmore Island has an extensive former raised shoreline. At least two former raised shorelines are represented on Ardmore Island. The site isdesignated an SSSI according to its geological importance. The contact zone betweenthe Palaeozoic Upper and Lower Old Red Sandstone is represented and outcrops onthe north-west corner of the island. The c. 30m high cliff has a distinct wave-cutnotch at its base showing that this feature is an earlier shoreline that has risen wellabove the present beach level as a result of isostatic uplift. A sea cave is present atNS 3150 7873. The coastal edge in front of the cliff is heavily planted with estatewoodland. Erosion Class: This section of coastline was found to be undergoing coastal erosion.At Craigendoran Railway station and to the east, the sea walls protecting the railwayline are undergoing local erosion. The principal factors involved here are wave actionand scouring at the base of the weaker sandstone fabric associated with the olderashlar sea defences. Erosion is more active at the junction of the sandstone ashlarstonework and the more recent concrete seawall, especially where remedial repairs arefailing. The coastline near Ardmore Crossing (NS 3240 7930) is predominantly saltmarsh which is eroding. Building rubble has been dumped at one location where theerosion is close to a field. Built Heritage & Archaeology: The archaeology in this area is minimal above thehigh water mark. Within the intertidal area a large rectangular fish trap is present.The size of the trap suggests that this feature functioned as a small industry rather thanas an opportunistic venture. A ruined cottage overlooks the fish-trap and it is highlyprobable that at some period in the past the occupants of this site managed the fish-trap. Both broad and narrow rig is present at Ardmore and are in parts truncated bythe modern footpath and affected by coastal erosion. A small concrete shelter wasalso seen in the hinterland, badly deteriorated, and is associated with a WWII lookoutpost. The principal feature is the remains of a large fish trap situated on the north sideof the island. The interior of the above mentioned sea cave was found to be empty.In front of the entrance a large mound of spoil rich in midden material was seen. Thisis the remains of interior cave floor layers excavated in the 1960s and finds includedIron Age pottery.
