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.
