--- The HRSC obtained these images during orbit 922 (7 October 2004) with a ground resolution of approximately 14.3 metres per pixel On the basis of crater-size frequency distributions on the valley floor and surrounding terrain it has been shown that the formation time of the valley amounts to approximately 350 million years. Determinations of discharge (valley) volumes on the basis of high-resolution HRSC derived digital terrain models reveal discharge rates that are comparable to those of the middle reaches of the Mississippi river in the USA. --- Summary: Between 3.5 billion and 3.15 billion years ago --> a "Mississippi-like" river carved a 400 kilometer long valley -------------------- - blue_scape / Nico -
