Shoemaker crater

Shoemaker (formerly known as Teague crater) is a meteor crater in Western Australia, Australia. The Shoemaker impact structure lies in the arid, central part of Western Australia near Wiluna.

It is 30 km in diameter and the age is estimated to be 1630 ± 5 million years. Crater contains seasonal lakes that produce salt deposits as they evaporate. The crater is exposed to the surface. Crater is regarded as the oldest known Australian impact structure to date. A dark, crescent-shaped inner ring surrounds the core, which consists of uplifted granitic rocks. The outer ring is composed of Precambrian sedimentary rocks.

It was renamed after the late planetary scientist Eugene Shoemaker.
