Dorothee Island (French: Ile Dorothee) is an island in the Australian state of South Australia which is part of the Pearson Isles which itself is part of the larger island grouping known as the Investigator Group. It is located about 69 kilometres (43 mi) west south-west of Cape Finniss on the west coast of Eyre Peninsula. It was discovered as part of the Pearson Isles by Matthew Flinders on 13 February 1802. The island was given its name in August 1969 in order to preserve a name used within the locality by the Baudin expedition. The island has enjoyed protected area status since at least 1972 and since 2011, it been part of the Investigator Group Wilderness Protection Area.
Dorothee Island is located about 4 kilometres (2.5 mi) south of Pearson Island and about 69 kilometres (43 mi) west-southwest of Cape Finniss on the west coast of the Eyre Peninsula in South Australia. It is part of the island group known as the Pearson Isles. The island has an area of about 56 hectares (140 acres). The island has undergone extensive erosion with the result that a large crevasse bisects the island in the east-west direction, forming a pair of peaks. The north side reaches a height of 140 metres (460 ft) while the south side reaches a height of 102 metres (335 ft). The top of both peaks each “retains some pockets of soil, predominantly coarse and granitic but with small patches of calcareous sandy loam”. The island’s east coast is reported in 1996 as providing “enough shelter to allow a cautious landing in all but severe swells”.
Dorothee Island was formed along with the rest of the Pearson Isles about 10,500 years ago following the rise of sea levels at the start of the Holocene. Geologically, Dorothee Island and the other parts of the Pearson Isles are the summits of an inselberg partially concealed by sea level rise. Dorothee Island’s southern and western sides fall to water depths greater than 50 metres (160 ft) within 500 metres (1,600 ft) from its shoreline.
