			Scenes of the Thaumasia quadrangle

	The Thaumasia quadrangle, is famous for showing us a good example of possible past rainfall and rivers in pictures of Warrego Valles taken with [[Mariner 9]] and the Viking Orbiters. Those early images revealed a network of branching valleys. They were clear evidence that Mars may have once been warmer, wetter, and perhaps had precipitation in the form of rain or snow. Before we saw those pictures, we believed Mars was just an old, dry desert.
