On Gunaikurnai Country. Named by Angus McMillan in 1840, an area near Bairnsdale. Kylie Carman-Brown noted that Scottish migrants named many sites in Gippsland as morasses, indicating sites with fresh water, where reeds and small trees may be present. She also noted that it can reflect the 'physical nature of this type of landscape', that is it is a feature which 'impeded their progress'. McMillan named it after nearly losing his favourite horse, Clifton, in the boggy landscape.
