Gale (crater)

Gale is a crater on Mars near the northwestern part of the Aeolis quadrangle at . It is in diameter and estimated to be about 3.5-3.8 billion years old. The crater was named after Walter Frederick Gale, an amateur astronomer from Sydney, Australia, who observed Mars in the late 19th century. Aeolis Mons is a mountain in the center of Gale and rises high. Aeolis Palus is the plain between the northern wall of Gale and the northern foothills of Aeolis Mons. Peace Vallis, a nearby outflow channel, 'flows' down from the Gale crater hills to the Aeolis Palus below and seems to have been carved by flowing water.
