If you followed the Edgar Rice Burroughs' John Carter of Mars novels, you read about a dying planet, drying up, a place that would, in time, become uninhabitable. Now Burroughs expressed an early 20th century vision of Mars, possibly with a network of canals. Too bad the process of beaming Carter from Earth to Mars didn't also take him back through time; it would have made the story more credible, but nothing saved the movie version from failing big time at the box office (I liked it anyway).
In any case, new evidence appears to confirm the existence of ancient streams on the surface of Mars:
