CLYDE MAP 6: ERSKINE HARBOUR to north of DOVE COTTAGE Hinterland Geology and Coastal Geomorphology: The hinterland is dominated by marine deposits resting on undifferentiated glacial till. The foreshore fronting Erskine Park is mainly marine mud flats. Degrading saltmarsh is present towards Dove Cottage. Erosion Class: This section of coastline was classified as both accreting and eroding. Marine mud is building up in parts at the MHWM and being displaced through the tidal cycle. Built Heritage & Archaeology: This cell had a high concentration of archaeological sites including three prehistoric logboats, a prehistoric canoe, and three intertidal crannog sites. Other finds of timbers and posts also suggest prehistoric activity. A fish-trap was recorded at Longhaugh Point. Two find spots produced Roman coins and objects and a silver ring. Inland, Erskine House was noted as being in good condition and still in use as a hospital. FICL/876/0/27/7/04 141 of 219 CFA
