Science Question:
Can the use of topography, classification, surface history, and evidence of fluid flow support our search for signs that weather may have helped to produce new surface material on Mars?

Main Results:
We have determined the steepest slopes of the canyon walls are about 3 miles high in some places. We can see sand sheets on the tower walls and another image we can see is the pattern of the wind down in the canyon, which shows that a large volume of material was collected down in the canyon floor. When a meteorite hits Mars it will sometimes cause a new blanket of rock and dust to cover the surrounding area. This new blanket around the crater is called ejecta and that form the new surface. New layer can also come from a volcano or water flow. The other reason for a new surface could be that weather helps to form new material in the form of blowing dirt, dust and sand over an old surface or craters to form new ground.
