This synthetic oblique view shows Ophir Chasma, the northern most one of the connected valleys of Valles Marineris; north toward top of frame; for scale, the large impact crater top right corner is 30 km (18 miles) wide. Ophir Chasma is a large west-northwest-trending trough about 100 km wide. The Chasma is bordered by 4 km high walled cliffs, most likely faults, that show spur-and-gully morphology and smooth sections.
