HIGHLAND'S END. The Martian highlands stretch away toward the horizon in this view that looks south over Nilosyrtis. Directly in the center lies the mouth of a large channel that leads up to an ancient, sediment filled crater. The light patch at left center was a proposed landing site for the Mars Science Laboratory rover — but this site lost out to others elsewhere on Mars. No vertical exaggeration.
