About this work
Harmakhis Vallis is an approximately 800-kilometer long outflow channel located in eastern Hellas. The valley probably formed by a combination of surface collapse and flowing water. The edges of Harmakhis Vallis were enlarged by material slumping off the walls, and it was later filled with ice-rich material, similar to glaciers on Earth. This image shows part of the valley floor that filled with glacial ice.
