Interacting Fossae Segments East of Athabasca Valles

Athabasca Valles starts suddenly along the Cerberus Fossae and flows southwest for approximately 400 kilometers. The source region is divided into two lobes, each roughly centered on the fossae.

Understanding the possible volume and flux of water in the ancient past may help in learning how the flood channel formed.
