, (4) Southern Bight The Minas Basin forms the eastern part of the Bay of Fundy which splits at
Cape Chignecto and is delineated by the massive basalt headlands of
Cape Split and
Cape d'Or. The Minas Basin is divided into four sections: (1) the Minas Channel, from the shortest line between Cape Chignecto and the
Annapolis Valley Shore to Minas Passage, between
Parrsboro and
Cape Blomidon; (2) Central Minas Basin, from Minas Passage to the mouth of Cobequid Bay, the shortest line point between
Economy and the Noel Shore; (3)
Cobequid Bay which extends to the mouth of the
Salmon River; and (4) the Southern Bight, from the mouth of the
Avon River to the shortest line between Cape Blomidon and the Noel Shore. Several large rivers drain into the Minas Basin: the
Shubenacadie River,
Cornwallis River,
Avon River,
Gaspereau River, and
Salmon River. Lesser rivers include the
Canard River, Diligent River,
Farrell River, and the Debert River. Along the northern edge of the Minas Basin lies a chain of intermittent high-cliffed
basaltic bluffs and islands called the
Basalt Headlands. On the northern shore of the Minas Basin, around the
Gaspereau River, and around the
Salmon River, extensive areas of farmland have been created using
dykes with
sluices (one-way flow control valves), a form of
polderisation.
Tides Burntcoat Head, located on the "Noel Shore" along the south side of the Minas Basin, is the location of the highest tidal range ever recorded, exceeding (during a
spring tide only) and has one of the highest average tidal ranges every day. The waters of Minas Bay exchange with the main part of the Bay of Fundy through the Minas Channel which flows between Cape Split and Cape Sharp, creating extremely strong tidal currents. Near Cape d'Or, the turbulent collision of currents is known as the
Dory Rips. The water in Minas Basin is a dense and nearly opaque reddish brown due to large amounts of suspended silt which are continually churned by tidal currents. At mid-tide, the currents exceed 8 knots ( per second), and the flow in the deep, -wide channel on the north side of Cape Split equals the combined flow of all the rivers and streams on Earth together (about per hour). == Communities ==
