River valleys

  • Area around Northern Kasei Valles, showing relationships among Kasei Valles, Bahram Vallis, Vedra Vallis, Maumee Vallis, and Maja Valles. Location is Lunae Palus quadrangle

  • Branched channels in Thaumasia quadrangle

  • The branched channels seen by Viking from orbit strongly suggested that it rained on Mars in the past. Location is Margaritifer Sinus quadrangle.

  • Semeykin Crater with detailed drainage system. Location is Ismenius Lacus quadrangle.

  • Channels near the rim of Ius Chasma. Their pattern and high density suggest precipitation as the source of the water. Location is Coprates quadrangle.

  • Ravi Vallis was probably formed when catastrophic floods came out of the ground. Location is Margaritifer Sinus quadrangle.

  • Tear-drop shaped islands caused by flood waters from Maja Vallis, as seen by Viking Orbiter. Location is Oxia Palus quadrangle

  • Flat terrain near the north pole of Mars showing polygonal patterns.

  • Patterned ground on Mars at 45° North

  • These rings on Mars may have been caused by crust moving over steam produced by lava interacting with water ice.

Gullies

  • Crater wall inside Mariner Crater showing a large group of gullies

  • Gullies on one wall of Kaiser Crater. Gullies usually are found in only one wall of a crater. Location is Noachis quadrangle.

  • Gullies near Newton Crater. Location is Phaethontis quadrangle

  • Gullies near Newton Crater

Glaciers

  • Glacier moving down valley, then spreading out on plain. Location is Ismenius Lacus quadrangle

  • This is the terminal moraine of a glacier. For scale, the box shows the approximate size of a football field. Location is Hellas quadrangle

  • Radar studies indicate that this glacier contains mostly pure water ice. It is moving from the right. Location is Ismenius Lacus quadrangle.

  • Tongue-Shaped Glacier. Location is Hellas quadrangle.

Other

  • The white area is water ice that has been exposed by an impact. Location is Cebrenia quadrangle.

Famous quotes containing the word images:

    “It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past.... Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.”
    —George Steiner (b. 1929)

    “In an age of synthetic images and synthetic emotions, the chances of an accidental encounter with reality are remote indeed.”
    —Serge Daney (1944–1992)

    “What images are these
    That turn dull-eyed away,
    Or shift Time’s filthy load,
    Straighten aged knees,
    Hesitate or stay?
    What heads shake or nod?”
    —William Butler Yeats (1865–1939)
