Pregacial survivors… the highest on Colonsay. Christopher Somerville notes in his excellent book Life Between the Tides that the highest of the raised beaches here now stands 130’ above the present sea level due to post glacial uplift. Those at Uragaig and Kilchattan are also notable. These earlier sea levels have resulted in many former sea caves along the island’s coast being sites of very early habitation.
