Hale is a 150 by 125 km crater at 35.7°S, 323.4°E on Mars, just north of Argyre basin. It was created by an asteroid roughly 35 km across that impacted at an oblique angle about 3.5 to 3.8 billion years ago. The rim and ejecta are eroded and show smaller impacts, but subsequent deposits have covered up small craters within it.[1] On the southern rim of Hale, parts of the crater wall have moved downslope towards the crater’s centre. The surface shows a network of fluvial channels which may have been caused by running water.[2]
It is named after George Ellery Hale.
