Evidence of Running Water
Evidence such as this for running water on Mars is plentiful. But this evidence suggests that the nature of flowing water on Mars is nothing like it's terrestrial analog. The evidence is in the form of:
- large, tear-dropped shaped outflow channels
- river valley networks unlike terrestrial river valleys
- catastrophic floods, with associated shorelines, & canyon sediments
