The crater is approximately 467.25 km (290.34 mi) in diameter and can be found at 304.42°W 13.88°S,[1] in the Iapygia quadrangle.
Scientists were delighted to see branched channels in pictures taken with spacecraft that were sent in orbit around Mars.

An excellent group of these channels is shown in the picture below from the rim of Huygens taken with THEMIS.
[2][3] These minerals represent evidence that Mars once had a thicker carbon dioxide atmosphere with abundant moisture.
