2. Noachis Terra: Geological Interpretation Ravyn Vialpando, Annalisa Hansen, John Crooke, and Chris Worley Kickapoo High School, Springfield, Missouri January 16 th, 2013 “We choose to go to the ‘Poo not because it is easy…. but because it is hard”

3. Significance of Research The features found indicate ancient impact, and faulting processes along with other more recent processes that create a large history of the area and Mars. 01/29/20132

4. 3 Area of Study: Noachis Terra Coordinates 30 West to 30 East -20 South to -60 South

5. Methodology Our approach was to provide morphological and spectroscopic examination NoachisTerra and the formations to show past geological processes. Analyzed 80 high resolution images using CRISM, HiRISE, THEMIS, and MOC to Characterize Noachis Terra and various types of geological processes Priority was to determine the geologic processes that shape the region to optimize understanding of geological history and brief minerology of this region. 01/29/20134

6. Definitions Horst and Graben- refers to regions that lie between normal faults and are either above or lower than the area Aeolian- processes of wind and more specifically, to the winds' ability to shape 01/29/20135

17. Conclusion High resolution imaging from CRISM showed impact cratering to be the most predominate process found in this region. High resolution images from HiRISE allowed detailed analysis of Aeolian features which indicate the wind direction. High resolution imaging from MOC and CRISM show indications pit and crater chains are results of thermo karst movement away from the area due to faulting and jointing. High resolution images from CRISM allowed a geologic time scale based on relative dating. 01/29/201316
