During late Wisconsinan glaciation, the northern part of the Hermitage area was glaciated by Newfoundland-centred ice and the southern part by a small, complex, upland ice field, broken by nunataks. During deglaciation a lobe of Newfoundland ice dammed a lake at the head of Bay d'Espoir in which a series of small glaciolacustrine deltas were deposited. Valley glaciers from the southern ice cap reached the south coast at several locations, most notably near Harbour Breton, where a large glaciomarine delta was formed during deglaciation when sea level stood 22–24 m above present HWM. Except for three occurrences of till, no deposits were found that can be attributed to glacial events older than late Wisconsinan.
