A closes examination of geological context Gale Crater the landing site of the Mars Science Laboratory Curiosity shows that the impact probably trigger an eruption of underground water that resulted in the dark regions which are probably a result of hematite rich soil. The southern part of the crater shows only a little evidence of water inflow but enough it was probably a result of overspill flowing back into the crater. Un like the Meridiani Planum region there is no real evidence of a real inflow channel. There is semi dark area supporting the idea of an overspill. Other than the three small backflow areas the rest of the southern rim shows the up wart fracturing seen in many other craters. The northern end however shows some evidence of considerable out flow. The two fan like structures come out from under
