Description

Troubridge Point is about 11 kilometres (6.8 miles) south west of Edithburgh. It is the most easterly point of the Yorke Peninsula coast that directly adjoins Investigator Strait. It is the termination for a pair of coastlines - one extending from Cape Spencer in the west and the other extending from Sultana Point from the north in Gulf St Vincent. It is the western end of the opening to Gulf St Vincent. [1] As of 2014, the point was located within the locality of Honiton. [2] [3] [4] [5]

Formation, geology & oceanography

Troubridge Point was formed when the sea reached its present level 7,500 years ago after sea levels started to rise at the start of the Holocene. [6] The cliff line which includes Troubridge Point consists of a sedimentary rock called Port Willinga Formation. [7] The water adjoining Troubridge Point drops to a depth of 10 metres (33 feet) at the base of its cliff face. [8]

Economic activity

As of 2014, the land adjoining Troubridge Point is used for farming. [9]

Gulf St Vincent A large inlet of water on the southern coast of South Australia between the Yorke Peninsula and the Fleurieu Peninsula

Gulf St Vincent, sometimes incorrectly referred to as St Vincent Gulf, St Vincent's Gulf or Gulf of St Vincent, is the eastern of two large inlets of water on the southern coast of Australia, in the state of South Australia, the other being the larger Spencer Gulf, from which it is separated by Yorke Peninsula. On its eastern side the gulf is bordered by the Adelaide Plains and the Fleurieu Peninsula. To the south it is defined by a line from Troubridge Point on Yorke Peninsula to Cape Jervis on Fleurieu Peninsula. Its entrances from the southwest are from Investigator Strait, and to the southeast from Backstairs Passage, which separate Kangaroo Island from the mainland. Adelaide, the South Australian capital, lies midway along the gulf's east shore. Other towns located on the gulf, from west to east include Edithburgh, Port Vincent, Ardrossan and Port Wakefield and Normanville.
