	==Inverted Terrain==		==Inverted Terrain==

			Unlike the Earth, Mars shows landscapes that are billions of years old. In that time material has been deposited and then eroded and/or greatly changed. Some features have been “inverted.” Low areas turned into high areas. Low areas like stream beds were filled with erosion-resistant materials like lava and large rocks. Later, the surrounding, softer ground became eroded. As a result, the old stream bed now appears raised. We can tell it was originally a stream bed since the overall shape from above still looks like a stream with curves and branches.

			In this article, some of the best pictures from a number of spacecraft will show what the landscape looks like in this region. The origins and significance of all features will be explained as they are currently understood.

			Scenes of the Iapygia quadrangle

	The Iapygia quadrangle covers the area from 0° to 30° south latitude and from 270° to 315° west longitude (90-45 E). Parts of the regions called Tyrrhena Terra and Terra Sabaea are found in this quadrangle. The largest crater in this quadrangle is Huygens, Some interesting and significant features in this quadrangle are dikes.<ref>Head, J. et al. 2006.
