the largest closed lake in southern Australia. Lake Eyre is located in a depression 12 m below sea level in an arid, desertlike region. It is filled with water only during the summer, when creeks flow into it periodically until it attains an area of 15,000 sq km and a depth of as much as 20 m. At other times it is a salt marsh. The lake was named in honor of E. J. Eyre.
a peninsula in southern Australia between the Great Australian Bight and Spencer Gulf. Plains and depressions predominate, the maximum elevation being 200 m. The vegetation consists of thickets of brush eucalyptus and heaths. In the north the Gawler Ranges rise to a maximum elevation of 496 m. Sheep are raised on the peninsula, and iron is extracted at the Iron Knob and Iron Monarch mines. The promontory was named in honor of E.J. Eyre.
